When Should You Use Your Parking Brake

by

Your car’s braking system is one of the most essential mechanisms built in for safety. Imagine driving down the mountain after a day of skiing without it. Even coming to a stop for a stoplight would be a harrowing experience if something were to go wrong.

While your front and rear brakes make up the most important part of the braking system, there’s a third brake that doesn’t get as much attention yet is equally important: the parking brake. The parking brake is connected to the rear brake system, and is used mainly as a failsafe if something were to happen to your brakes during your normal drive.

The parking brake is a secondary brake system that is designed to be independent of the front and rear brakes. This is your safety feature. You’ll find the control for your parking brake in one of four places:

  • Center console – it’s a lever located between the two front seats
  • Foot pedal – it’s a pedal located on the floor on the far left of all other pedals
  • Stick – in older vehicles, you may find the emergency parking brake lever located on the instrument panel
  • Push button – on newer vehicles, a push button exists on the console with other components

The mechanism is available for easy access.

If you drive a manual transmission, you may be used to using a parking brake to keep your car from rolling. But that doesn’t make a parking brake on an automatic transmission any less important. In truth, everyone should be familiar with the uses of a parking brake, and utilize it to make your driving experience safer.

How a parking brake works

When Should You Use Your Parking BrakeYour vehicle’s brakes are designed to bring your car to a stop. The more pressure you apply to the brake pedal, the more tension is transferred from the brake pad to the wheel, slowing your car until it eventually stops.

When you engage the parking brake, discs inside your rear wheel squeeze up against the inner part of the wheel in much the same way. This action slows the wheel, eventually stopping it and keeping it from rolling away.

While parking brakes work in a slightly different manner from vehicle to vehicle, to engage the parking brake, fully engage the rear brake system by pressing down on the brake pedal. Only then should you pull the lever or press the button for the parking brake system. Once the parking brake is in place, shift your car into park. Then release the brake pedal. This allows the hydraulic system to activate and do its work without putting added stress on the transmission.

Why your vehicle has a parking brake

In everyday situations, you might be tempted to only utilize your vehicle’s braking system. When you place your vehicle in park, a parking pawl is pushed into one of the grooves of the transmission gear to keep it from moving. A parking pawl is nothing more than a hammer-shaped pin that drops into place. While it might be enough force in everyday situations, it can weaken over time, especially if you’re on steep inclines or hills. One small pin stopping a several ton vehicle will only work for so long.

If you don’t use your parking brake regularly, this parking pawl weakens over time. That can impact your transmission system, or cause accidents as your vehicle rolls away. That can lead to expensive repairs.

Get in the practice of using your parking brake

Even if you infrequently drive, even if you park in relatively flat areas across the Front Range, your vehicle can still be at risk. If you’re putting your car in park, it’s a good idea to engage the parking brake too.

We advise using a parking brake no matter where you park your vehicle, but especially as your risk level increases.

Are you parallel parking on a hill? Engage your parking brake.

Are you filling up your vehicle at a gas station? Engage your parking brake.

Will you be leaving your car in a parking garage for hours at a time while you head into the office? Engage your parking brake.

It’s better to be safe than sorry. And a parking brake gives you added insurance to ensure your vehicle stays safe.

In many cases, people refer to a parking brake as an emergency brake. That title may be a bit misleading, making you think you only need it in emergency situations. The parking brake not only keeps your vehicle from moving, but it also saves your transmission from wear and tear. And that can save on repair bills down the road.

Using a parking brake in an emergency

Your car’s braking system is a complex mechanical system. Over time, it can fail, and that could be catastrophic depending on where it happens. That’s where the emergency brake comes into play. If you’ve ever referred to the parking brake as an emergency brake, this is why.

In the case of brake failure, you have seconds to react. A natural reaction is to stomp on the parking brake pedal, or pull up on the parking brake lever as hard as possible. Resist that urge. That will send your car into a tailspin, and possibly put you in even more danger.

Instead, slowly engage the emergency brake as your car comes to a stop. The parking brake is designed to hold your car in place, not stop it. As it engages, it slows your vehicle down until the point you can gain control.

Get a full brake inspection

If the concept of using your parking brake regularly is still new to you, put it into practice today. It can help your vehicle have a longer lifespan, as well as keep it safer over time.

Have a question about how well your brakes work? It’s time for a complete brake inspection. It’s the easiest way to determine how safe your entire braking system really is. By bringing it in, we can tell you how much wear is left on your brake pads, and give you tips on better driving and maintenance. If you pinpoint issues early, you’ll stay safer in the long run.

What Your Parking Brake Is For

by

There are a lot of parts to a car that we tend to take for granted. They’re there. We may use them from time to time. But we rarely think much about them.

That defines the parking brake perfectly.

The parking brake is designed for what its name suggests: to add extra security to your vehicle when it’s stopped, resting, and you’re away from the car. Of course, that’s not it’s only function. Which is why it is sometimes referred to as an emergency brake, e-brake, or hand brake too.

When you think parking brake, think safety. That’s what it’s designed for. But what is its true function?

Let’s start at the beginning.

How does a parking brake work?

A parking brake is a part of a car’s braking system. It connects to the rear brakes, and when engaged, engages the vehicle’s primary braking system with less force.

Looking back at history, the parking brake was an important part of the braking system. It was designed to give a driver another option to stop the car if, by chance, the hydraulic brakes fail while driving.

What Your Parking Brake Is ForOn modern cars, however, the parking brake is rarely needed in that circumstance. That could be why the name has morphed over time from the emergency brake to the parking brake.

While your primary brakes operate through a technology-driven hydraulic system that gradually brings your car to a stop, the parking brake is designed to hold your car in place.

Today, we use the parking brake as an extra precaution for keeping our vehicles motionless while parked. This can be a big benefit when parked on steep inclines or declines.

As our vehicles get more sophisticated, the way systems operate is changing too. In general, there are four different types of parking brake systems. You can check your owner’s manual to confirm what comes equipped on your vehicle.

  • Stick lever – on older cars, you’ll find this located on the instrument panel
  • Center console lever – this is located between the two front seats
  • Foot pedal – this is located on the floor on the left side of the pedals
  • Push button – with newer cars, you’ll find the parking brake can be activated by a button located somewhere on the console

When should you use your parking brake?

As the name implies, a parking brake should be used whenever you park your car. Whether you drive with manual or automatic transmission, the parking brake adds extra security when you walk away from your car.

While some will tell you that parking brakes are more important when you park on an incline or decline, others will tell you it’s equally important to use it no matter where you place your vehicle. Your braking system uses a device that keeps your brakes locked and engaged whenever you put your car into park and walk away. However, failure can occur, and it’s not just the brakes that can cause the problem. If the gears aren’t engaged, it can cause your car to roll, even on what appears to be a flat surface. Engaging it each and every time you turn off your car ensures your car stays where you place it.

Here’s a tip for reducing the stress on the drive train. If you are parking on an incline or decline, leave your foot on the brake pedal as you move the gears to park position. Before you take your foot off the brake pedal, engage the parking brake too.

Have you ever let your foot off before engaging the parking brake? Have you felt your car jolt forward or backward as it adjusts to sitting on an incline? That action over time can damage both your transmission and braking systems. That means costly repairs before their time. Engaging the parking brake first prevents this action from occurring, protecting various systems throughout your vehicle.

When you’re ready to drive, start your engine, press down on the brake pedal to engage the brake system, release the parking brake, and then move into drive. Driving with your parking brake on can damage your vehicle.

Why is a parking brake important?

Get into the habit of using your parking brake every time you stop. It gives you added stability while your vehicle is inactive. While this can be important to keep your vehicle stable while resting on an incline, there are other circumstances where this is important too.

For example, if you’re sitting on a busy street or in a parking lot, and someone hits your vehicle, the parking brake decreases the chance of it rolling, increasing the likelihood of damage.

It also keeps your car in overall good working condition. If you don’t use parts, they start to wear. A parking brake that is rarely used can stiffen, rust, corrode, weaken, and wear down, meaning it’s less likely to work when you need it most.

Like every part of your car, it’s important to have the parking brake regularly inspected to ensure it’s in proper working condition.

Potential problems with your parking brake

While parking brakes rarely present problems, you may likely find yourself in one of these situations:

Parking brake frozen – ice can cause the parking brake to freeze when it’s really cold. Leaving the engine run for a few moments can start to heat your car and make the ice melt. If this doesn’t melt it, you can find which wheel it’s connected to, and melt the ice with a hairdryer.

Rust or corrosion – over time, corrosion or rust can infiltrate the mechanism inside the parking brake, making it harder to work until it freezes altogether. It might be difficult to diagnose without having it towed in. You can apply and release the brakes a few times to see if you can disengage it. Shift between reverse and drive to see if it loosens up the debris enough to take the parking brake off. If not, your only choice is to have it towed and repaired.

Engaged too hard – when people are in a hurry, they often make quick movements that can hurt more than help. That’s often the case with the parking brake. If you pull up too hard, it can jam it. Pulling with all your strength can get the brake shoe stuck in the wheel drum. It can stretch out the cable that runs from the wheel to the brake handle enough that makes it impossible to disengage. If you’ve tried and can’t release the parking brake, it may be time to seek help.

Whether you have a question about a specific problem, or just need an inspection and check up to keep you on the road safely, we can help.
