Brake System Service

by 2 Comments

The last thing we need in this fast-paced life we live in, is to have trouble ” putting on the brakes!”  We can all benefit from slowing down and enjoying the ride every now and then.  And just as we need to engage our “life brakes” we also need to be able to use the brakes on our vehicles.  Sometimes this can be a challenge if our brakes haven’t been taken care of properly.

If the brakes on your vehicle are not working properly, or if the brake pedal seems soft or spongy, it might be time you looked into having a brake system service.

The brake system is the most important safety system on your car.  The brake fluid used in your vehicle transmits pressure from the driver’s foot to the wheel cylinders, that pressure is then converted into a frictional braking force on the wheels.  The frictional braking creates heat that can get transferred to the brake fluid itself. In order to operate properly, it is important that the brake fluid isn’t allowed to boil, even when this heat is created.  To make sure it doesn’t boil, your brake fluid must be free of contaminants. Contaminants, including moisture can lead to early failure of brake components.  Moisture absorbed by the brake fluid also causes the brakes to feel soft, spongy or to lose your brakes altogether.   This is why we recommend a brake system service.  Regularly changing the fluid in your brake system can improve the performance of the braking system and reduce the chance of costly repairs due to the failure of brake components because of fluid contamination.

When we perform a brake system service, one of our technicians will remove all of the existing brake fluid in the master cylinder using a specialized brake fluid service system.  This brake fluid service system is connected to all four wheels and will completely flush and refill the entire brake system and master cylinder.

Give us a call at (303)691-2760 or come in and see us if you’re having a little trouble “putting on the brakes” or for any of your other auto repair needs.

 

 

Auto Repair-Brakes

During the winter months when the weather is constantly changing here in Colorado and you never know for sure what the driving conditions will be for each day, it’s very important to stay current with our auto repair, especially when it comes to our brakes.  Existing brake problems can become worse in the winter when we are driving in conditions that cause traction to be reduced.  Bring your vehicle in and have the brakes inspected to make sure they will perform correctly and keep you safe while you are driving in winter weather.

The simplest way to keep your brakes from failing is to have your vehicle  regularly maintained.  It’s also important to listen carefully to your car.  Brakes will squeak, click or grind when there is a problem, its just a matter of listening and discovering when the noises change.  Take note of any changes.  As well as hearing squeaking or grinding noises when you apply the brakes, you might feel a pulse in your brake pedal, or a grabbing or pulling to one side or the other.  These are all indications that it might be time to stop in at the auto repair shop and have the brakes checked out.

Having your brakes inspected regularly is the best way to avoid brake failure.  But sometimes despite our best efforts, something happens and the brakes fail!   In case this happens to you, here are some tips that might help make the experience a little less frightening.

  1. Don’t panic.  The calmer you remain, the more likely you will be able to steer your vehicle to a safe stop.
  2. Turn on your turn signal and carefully try to get your vehicle to the right lane.  Watch your mirrors so you can avoid hitting another car.
  3.  When you reach the right lane, put on your hazard lights.  This will let other drivers know that you are having a problem and allow them to steer away from your car.
  4. Take your foot off the gas pedal, downshift to a lower gear and allow the car to slow down.  You can downshift even if your car doesn’t have a manual transmission, move the shifter from “Drive” or “D” to “Low” of “L”.
  5. Steer your car onto the right shoulder of the road, and then shift your vehicle into neutral.  Gradually apply the hand brake (emergency brake) until the vehicle comes to a stop.  Pull the hand brake slowly to keep control over the vehicle.

When To Flush Your Brake Fluid

by Leave a Comment

Did you know that you should flush your brake fluid regularly?  Most of us don’t know when to flush our brake fluid or why we need to do it.

Brake fluid attracts moisture, and when moisture enters the brake fluid system, it creates some hazardous conditions.

  1. Moisture forms acid that attacks the rubber seals and keeps them from sealing properly.
  2. Moisture creates rust and corrosion that can become clogged in small passages and causes engine parts to seize.
  3. Moisture reduces the boiling point of brake fluid.  When brake fluid boils it changes from a liquid to a gas, this  prevents the brake fluid from doing its job correctly.  It can only perform effectively if it remains a liquid.  If your brake fluid boils, a vapor is created that reduces the amount of pressure that’s applied to the brake pads.  If this happens, you can push the brake pedal all the way to the floor and still not be able to stop your vehicle.

This moisture was not a huge issue ten years ago, but on ABS brake systems of today, the rust and debris that collects in the fluid can cause internal damage and be very costly.  For more information on ABS systems check out our blog.

So how do you know when to flush your brake fluid?  Have your technician check the three C’s:   color, clarity, and content.  The color of your brake fluid should be a light amber.  The clarity should be clear, which means it shouldn’t have any particles or debris in it.  And the moisture content should be less than 3 percent.

According to AAA, many cars on Colorado roads today, were built by European automakers and require regular brake fluid inspections, which about half the cars fail.  Such inspections aren’t required here, but someone needs to monitor the color, clarity and moisture content of a vehicles brake fluid, either the owner or better yet, a professional!  Brake fluid flushes are recommended every two years by industry standards, sooner if you live in a humid climate.  Check with your technician and discuss what works best for you and your vehicle.

Brake Problems

by Leave a Comment

In Roseville  Michigan, a twenty-four year old man tried to use his feet to stop his runaway truck that had serious brake problems.  After his brakes failed on a busy street in Roseville, about two miles north of Detroit, the man was unable to use his brakes to stop.  So he continued driving but stuck his feet outside the truck in a futile attempt bring the truck to a stop.  Witnesses said the man reached speeds of about 40 mph and struck two cars after going through a red light.  He continued on and was eventually able to bring the truck to a stop but not before he had hit two more vehicles!

Then there was the firefighter that experienced brake problems when he was approaching an intersection while returning from an early morning alarm.  The vehicle was going less than 45 mph and the roads were clear but the temperature outside was near 9 degrees.  He tried to gear down but the automatic transmission didn’t work and there were two cars waiting for the light on either side of the intersection.  Fortunately, he was able to move as far to the left as possible as he approached the intersection and he made a wide right hand turn onto a two lane road and was able to come to a safe stop in an empty parking lot!

Don’t let this happen to you!

Although brake failure accidents are very rare, ( they consist of 5% or less of car accidents per year) we certainly don’t want to be included in that 5%.  So take the steps necessary to maintain your brakes properly and prevent brake problems from turning ugly.  There may be no sure way to prevent the possibility of a brake failure accident, but you can make sure to do your part.

Make sure that your brakes are inspected and serviced regularly.  If there is a recall notice for your vehicle, affecting the brakes or anything else, take it seriously and don’t ignore it.

Listen for grinding or squeaking noises when using the brake, or difficulty actually stopping the car.  Also be aware if your car veers to one side or the other when you put pressure on the brake pedal.  And last but not least, don’t neglect your brake fluid.  Most experts recommend that you completely change the brake fluid every one to two years.  Brake fluid that has been in the car for a year may contain 2% water, which greatly decreases its effectiveness.

How Often Should I Change My Automotive Brakes?

by 1 Comment

This month we have been talking about brakes and we are often asked the question, “how often should I change my automotive brakes?”  Here are a couple of things to consider. 

Brake Pads

Brake pads typically come with a warranty – you may see a lifetime warranty, or more commonly, a warranty based on mileage, such as a 10,000 mile warranty.  Lifetime warranties aren’t meant to last a car’s lifetime.  Auto parts manufacturers use that terminology because brake pads do last a long time, but most car owners will trade and purchase a new car long before their brake pads need replacing.

Regardless of the terminology, it’s more important to listen to your car instead.  When you apply the brakes, you can hear the sounds of a worn brake pad.  If you hear a grinding noise or a squeak, its time to replace the brake pads, regardless of the mileage.

Rotors

Brake rotors, or brake discs, are what your vehicle’s brake pads clamp down on, and what stops the wheels from spinning.  Like brake pads, there are different types of rotors, depending on your car and driving needs.

Unlike brake pads, rotors do not need to be changed on a regular basis, and should last indefinitely if you provide regular maintenance routines on your automobile.  Rotors will be damaged if you allow your brake pads to wear down, and drive without the use of pads for an extended period of time.  The grinding noise you begin to hear from the brake pads is an indication of the screws in the base of the brake pads grinding into the groove of your rotor.  The more it continues to grind, the greater your chance of having to replace your rotors.

Do you want to keep your automotive brakes in top condition?  Have them checked and replaced on a regular basis.

Service Brake System

by Leave a Comment

If it’s time to service your brake system you will notice the following symptoms and conditions:

  • Soft or spongy brake pedal
  • Brakes not working properly
  • Manufacturers recommendation

Once it has been determined that you need to service the brake system on your vehicle, a skilled technician will perform the following procedure:  

  • Remove all of the existing brake fluid in the master cylinder using a specialized brake fluid service system.

This brake fluid service system, which is connected to all four wheels at the same time, will refill the master cylinder with high quality new brake fluid after the old brake fluid has been completely flushed from the entire brake system.  The old contaminated brake fluid is removed at each wheel until new brake fluid has completely filled the system.

Your brake system benefits from this service because as brakes are used they generate heat and the brake fluid needs to remain liquid, without boiling, to operated properly.  Over time, brake fluid can become contaminated.  Contaminants, including moisture can lead to early failure of brake components.  The moisture absorbed by the brake fluid causes the brakes to feel soft, spongy, or not work properly.

The brake system is the most important safety system on your car.  By regularly changing the fluid in your brake system you can improve the performance of the brake system and reduce the chance of costly repairs due to brake failure from brake fluid contamination.  The contamination and deterioration of the brake system can be a gradual process.  While you may not notice any problems, it is a good idea to take preventative care of your brake system to help prevent future costly repairs.

Brake Specialist – Understanding How Your Brakes Work

by 1 Comment

When you’re driving in your car, and push down on the brake pedal, we unconsciously know it’s going to work.  But how does it work?  And more importantly, what do you watch for to make sure they keep working for you?  Those are questions a brake specialist deals with every day.   

Your car’s brake system is a complex system of parts and components that spreads all along your car.  The easiest way to avoid brake failure is to maintain your car, and to listen to your car’s system regularly.  Your brakes squeak, click and grind – its just a matter of listening and discovering when the noise changes.  And using a brake specialist to keep you on a regular maintenance schedule.

In your car, the brake pedal is connected to the pistons, and the pistons are connected to the brakes.  Your car will have two sets of brakes:  disc front brakes and drum rear brakes.  In both sets, friction is used to control and stop the car when you require them.  Several things can interfere with the friction, leading to failure:

  • An oil leak can eliminate the friction within the braking system
  • If brakes routinely overheat, they can create hard spots in the brake rotors or drums.  These hot spots resist friction, reducing the grasping mechanism within the brake system.
  • A squeaking noise can indicate thin or wearing brake pads.  Replacing brake pads early can prevent future maintenance.  If pads wear down  to the rotors, it can cause further damage, and cost even more to replace.

Take notice of your cars messages.  Your anti-lock brake system (ABS) light will come on at the first sign of damage.  You may also start hearing squeaking or grinding noises when you apply the brakes.  Or you begin to feel a pulse in your brake pedal, or a pull or grab to one side or the other during the braking process.

Instead of waiting or ignoring the problem, check in with your brake specialist today.

Antilock Brake Systems

by 1 Comment

It wasn’t until we almost had a major accident on a recent trip in the mountains that I realized the importance of antilock brake systems.  We were on our way home from a day of skiing.  We were moving along at a pretty good speed, considering we were on I-70 at the same time as thousands of other cars, when almost instantly the car in front of us stopped.  If we didn’t  have antilock brakes (ABS) we would have had one big mess!

This is how antilock brake systems work.  ABS works with your regular braking system by automatically pumping them.  In vehicles not equipped with ABS, the driver has to manually pump the brakes to prevent the wheels from locking up.  When your wheels lock up on wet and slippery roads or during a panic stop, (like ours) you may lose traction and control, causing your vehicle to spin.  Antilock brakes keep your wheels from locking up, so your car maintains directional control and you can steer around hazards, if you can’t make a complete stop in time.  If your vehicle has ABS, your foot should remain firmly planted on the brake pedal, while ABS pumps the brakes for you so you can concentrate on steering to safety.  An ABS automatically changes the brake fluid pressure at each wheel to maintain optimum brake performance.  There is an electronic control unit that regulates the brake fluid pressure in response to the changing road conditions or an impending wheel lockup.

There is more than one kind of antilock brake system.  Four-wheel systems, including those found on cars and minivans, are designed to keep all four wheels from locking up.  Rear-wheel only systems, found on some pickups, vans and SUV’s, keep the vehicle from spinning out of control, but the front wheels may lock up, resulting in a loss of steering control.

Some of you may be asking if vehicles with ABS stop more quickly than those without.  Perhaps, but the main purpose  the Antilock brake system was designed for is to help you maintain control of the vehicle during emergency braking situations,  not necessarily make the car stop more quickly.  ABS may shorten stopping distances on wet or slippery roads and most systems may shorten stopping distances on dry roads.  On very soft surfaces, like gravel or unpacked snow, ABS may actually lengthen stopping distances.  In wet or icy conditions, you should still keep a safe distance behind the vehicle in front of you and drive carefully keeping the road conditions in mind.

To find out whether your car has an antilock brake system and what type, check your owner’s manual.  You can also check your instrument panel for a yellow ABS indicator light that appears after you turn on the ignition.   For more information about driver’s safety call the NHTSA Auto Safety Hotline at 1-800-424-9153

Brake Fluid Change

by Leave a Comment

Brake Fluid ChangeReader Question: I took my truck in for a routine oil change.  The mechanic said I needed a brake fluid change because it was dirty and needed flushing because of the ABS anti-lock brakes.  I’ve never heard of this before.  Why do I need a brake fluid change?

Dear Reader: Clean brake fluid is vital in keeping your brake system working properly.  Brake fluid shouldn’t freeze or boil, but as soon as it is put into the brake system it starts to absorb moisture.  The fluid attracts moisture through microscopic pores in the rubber hoses or seals and through exposure to the air.  That moisture is very damaging to the brake fluid.  After only one year of service, the brake fluid in an average vehicle might contain as much as two percent water and it  takes very little  moisture to make the brake fluid less effective.  The heat generated by normal and especially hard braking makes the moisture in the fluid boil and that causes the brakes to loose their effectiveness.  Also brake fluid that is contaminated with moisture and dirt (if moisture can get in than so can dirt) can have a drastic effect on braking systems that use anti-lock brakes.  The contaminants can ruin the delicate inner parts of these systems, which are extremely expensive to repair.

Did you know that the average motorist who drives 10,000 to 15,000 miles a year uses their brakes about 75,000 times a year?  You would think that since drivers are using their brakes so much they would recognize the importance of having their brake fluid changed.  But probably half of all vehicles that are 10 or more years old, here in the U.S. have never had their brake fluid changed.  Just like you, they have never heard of it, or if they have, they have failed to see the importance of it.  Experts recommend having a brake fluid change every one to two years as a preventative measure.  We wouldn’t be doing our job if we didn’t agree.

Auto Brake Repair

In these days of difficult economic times, none of us want to be taken for a ride when it comes to having an auto brake repair.  The braking system in a car is a complex system that needs  proper maintenance and care throughout the lifetime of the car to keep you and your family safe.   It’s important to get the best information on auto brake repair so you don’t end up being cheated out of your hard earned money.

The best thing we can do to save us from brake repair is preventative maintenance.  Avoid “riding” your brakes.  It’s better to slow down with moderate pressure and then release the brake allowing them to cool, rather than riding the brakes and overheating them.  Also consider downshifting to save your brakes. Downshifting lets your engine do some of the braking instead of your brakes.  This should only be used when traction conditions are good.  In ice, snow, or even rain, downshifting into too low of a gear may cause you to skid.  Auto Brake Repair

Even when we are pro active and do our best to avoid a brake repair, normal daily activities cause wear and tear on our cars and can cause problems.

The most common problem with the braking system is wear.  Brakes do a lot of work and the brake pads take the brunt of the punishment.  It’s a good idea to have them checked every six months or more often  if you suspect a problem.  If there is squeaking, grinding or difficulty stopping there might be a problem.  Most brake pads have a thin metal tab which vibrates when the pads wear down to a dangerous level.  Some brake pads don’t have this tab and if they aren’t check periodically they can wear down far enough to ruin the rotors.

Another problem is warped rotors.  Rotors warp if the brake pads are bent, defective or incorrectly installed or if they are exposed to excessive heat.  A warped rotor will give a pulsing feeling when you are applying the brakes.  This pulsing can be annoying and dangerous, have  your car checked as soon as possible if this is occurring.

When you have made the decision to visit your mechanic, keep these things in mind.   Ask your mechanic to clean all the brake system components after they’ve completed your brake repair.  This ensures a dust and squeak free job.  Also ask your mechanic about using an anti-squeak compound on the back of the brake pads.  This can keep the pads from vibrating and annoying you.  And most importantly, watch out for shops that practice bait and switch.  Bait and switch is advertising a product on TV or in the paper at a low price  and then when you ask for that product or service they claim not to have it anymore but can get you something “better”.  This is how they lure you into their business so they can sell you products or services that you don’t really need.  You can keep your money and your car safe by educating yourself about auto brake repair.
