What’s that sound? Why are my brakes so touchy when I push down on the brake pedal? When your brakes have problems, you’ll know it by paying attention to a change in behavior.
That’s by design. Brakes are arguably one of the essential systems in today’s modern vehicles. Imagine coming off the mountain after a day of skiing without the ability to use your brakes. It would be a harrowing experience at best.
Still, how do you know what to do? Who should you trust? You know the cost of brake repair is going to take a bite out of your wallet. But what’s better: fix your brakes or replace them?
How brakes work
The braking system in a car is an essential safety feature that allows the vehicle to slow down or stop when the driver presses the brake pedal.
When the brake pedal is pressed, a lever called the brake pedal pushrod activates the master cylinder, a hydraulic pump. The master cylinder pressurizes the brake fluid stored in a reservoir. The pressurized brake fluid is then sent through a series of tubes and hoses to the brake calipers located at each wheel.
Inside the brake caliper, there are one or more pistons that are activated by the pressurized brake fluid. The pistons push against the brake pads and squeeze against the brake rotor. This creates friction, which slows down the rotation of the wheels, bringing the car to a stop.
The brake pads and rotors can get very hot during this process, so most cars are equipped with a cooling system to dissipate the heat.
Some cars also have a brake booster, a vacuum-assisted device that helps the driver apply the brakes more easily. The brake booster uses the vacuum created by the engine to multiply the force applied by the driver’s foot on the brake pedal.
The brake system converts the moving vehicle’s kinetic energy into heat energy through friction, slowing down the car and bringing it to a stop. It is a complex system that requires regular maintenance and inspection to ensure it functions correctly.
Signs your brake system has a problem
As a car owner, it is important to regularly check and maintain your vehicle to ensure its safety and longevity. One key component to check is your brakes, as they are essential to your car’s overall function and safety.
There are several signs that your car may be experiencing brake problems. Here are some things to look out for:
- Squealing or grinding noises: If you hear squealing or grinding noises when you apply the brakes, this could be an indication that your brake pads are worn down and need to be replaced.
- Soft or spongy brake pedal: If you press the brake pedal and it feels soft or spongy, this could be a sign that there is air in the brake lines or that the brake fluid is low.
- Vibrations when braking: If you feel vibrations in the brake pedal or steering wheel when braking, this could be a sign of warped brake rotors.
- Pulling to one side while braking: If your car pulls to one side while braking, this could be a sign of a stuck caliper or an uneven brake fluid distribution.
- Brake warning light: If the brake warning light on your dashboard is illuminated, this is a sign of a problem with your brakes.
If you notice any of these issues, it is vital to have your brakes checked by a mechanic as soon as possible. Neglecting to do so could result in further damage to your brakes, which can be costly to repair.
In addition to watching for warning signs, it is also important to regularly check your brake fluid level and to have your brakes inspected and serviced according to the manufacturer’s recommended schedule. This will help ensure that your brakes are in good working order and can help prevent more serious problems from occurring.
If you do need to have your brakes repaired, be sure to use a reputable mechanic and only use high-quality brake parts. Using cheaper, inferior parts can result in further problems down the road.
Should you fix your brakes or replace them?
How do you know if you should fix or replace your brakes? You can start by assessing the current condition of your braking system.
- Age of the brakes: If your brakes are older and have been in use for a long time, they may be more prone to wear and tear and may need to be replaced.
- Condition of the brakes: If your brakes are heavily worn or damaged, it may be more cost-effective to replace them rather than trying to fix them.
- Cost of repair: If the cost of repairing your brakes is close to or more than the cost of replacing them, it may make more sense to replace the brakes.
- Frequency of use: If you use your brakes frequently, such as in stop-and-go traffic or on hilly terrain, they may wear out more quickly and need to be replaced more often.
- Driving habits: If you have a tendency to brake hard or ride your brakes, your brakes may wear out more quickly and need to be replaced more often.
- Vehicle make and model: Some makes and models of vehicles may have brakes that are more prone to wear and tear, and may need to be replaced more frequently. Check your owner’s manual for more details.
- Overall condition of the vehicle: If your vehicle is older and has high mileage, it may be more cost-effective to replace the brakes rather than trying to fix them.
Ultimately, the decision to fix or replace your brakes will depend on a variety of factors, including your own personal situation. It’s always a good idea to have a mechanic inspect your brakes regularly to ensure they are in good working condition, and to replace them if necessary to ensure the safety of your vehicle.
Building a relationship with a reputable mechanic will give you the assurance you need to rely on their opinions, and make the right decision for your situation.
