It’s a good idea to get your brakes checked at every oil change, or at least twice a year, if your car is older than two years. As a result, recommending a replacement time frame or mileage requirement is problematic. The sort of driving you do, your driving style, and the amount of time you spend driving, all influence how long your car’s braking system lasts. We have compiled a list of some cool facts and tips about brake pads for those of you curious to know more about them. The effectiveness of the brakes is totally determined by the frictional substance used, which has an impact on the performance of the brake pads. Through friction, brake pads convert the vehicle’s kinetic energy into heat energy. They assist in a vehicle’s gradual deceleration until it comes to a full stop. One of these components is the brake pads.īrake pads are the most important component of a car’s braking system. Braking systems in cars, trucks, and motorcycles are made up of a variety of components that transform the driver’s motions into a physical force that brings the vehicle to a halt. If the vibration or pulsing continues, that is another sign they need to be inspected.There’s a lot more to the proper operation of your car’s braking system than hammering on the brake pedal when a squirrel leaps out in front of you. If you've been driving aggressively or using the brakes hard while descending a mountain road, this brake roughness might abate when the brakes cool. If you feel a vibration or pulsation in the brake pedal during normal braking, this means your rotors are warped and require truing to smooth them out-or possibly replacement. If your car pulls to one side during braking, the brakes may be wearing unevenly, there might be a leak in one of the brake lines, or you might have an issue with your steering or front suspension that's unrelated to brakes. If you have any of these systems or see a puddle of liquid left behind by your car when parked, see a trusty repair shop or dealer. This could be water or air in the brake fluid, a fluid leak in the system, or a failing brake master cylinder. If your brakes don't stop as readily as they used to, and if the pedal feels mushy, rather than firm, or slowly sinks toward the floor, there's likely another problem. There are other symptoms of brake trouble that don't involve wear to the brake pads. Have any squealing or grinding noises checked immediately. This situation will also destroy your brake discs and possibly cause the brake system to fail entirely. It reduces your stopping power significantly your brakes won't slow the vehicle adequately or possibly not at all if you let this go on for any length of time. If you hear a scraping or a deeper grinding noise, it could well be that the brake pads have worn down to their metal backing plates and that those plates are being squeezed directly against the steel brake discs. However, not all cars have this feature, which is called a mechanical brake-wear sensor or a brake scraper, so check to see if yours does. The noise is generally audible when the windows are up, but it may be masked by loud music or other environmental noise. The first is something you can hear: Once brake pads are worn to the point of needing replacement, a thin metal strip in the pads will make a screeching noise or squeal when you apply the brakes. How to Know If Your Brakes Are Worn Outĭisc brakes generally give a few clear indications that it's time for a brake job. Brake pads are an integral part of your car's disc-braking system, and making sure they are in good condition is crucial to your safety. As the pads rub against the rotors, they both wear down slowly the black dust you see on the wheels of some cars is the residue from the pad material and steel rotor that has worn off. The friction created is what cuts the speed and brings your car to a halt. When you push the brake pedal, it causes the calipers to clamp down on the brake pads, which squeeze the rotors, transferring the kinetic energy of your car into thermal energy-heat-via friction. Why Brake Pads Wearĭisc brakes slow and stop your car by using brake calipers (they're like large, adjustable clamps) to squeeze brake pads (they look a little like hockey pucks sawed in half) against the brake discs, also known as rotors (Frisbee-sized metal discs). You don't need the stress.īut how long do brakes last? And when should you replace them? Luckily, there are a few easy ways to know when it's time to get your brakes checked or replaced. It's a safety issue, and it's also about confidence: Feeling that your brakes aren't up to the task of stopping your car is plain unnerving. There's nothing more important on a car than properly functioning brakes.
