How do brake pads fail?
Pad wear is accelerated when the brakes don't release correctly. This is most commonly caused by seized brake caliper slider bolts, seized brake caliper pistons or by a buildup of dust inside the caliper.
Pad squeal can be caused by foreign objects getting embedded into the brakes, or from the lack of lubrication between the pad and the caliper. Some brake pads will start to squeal when the friction material is completely worn.
Many modern vehicles also include a brake pad wear sensor that is used to alert the driver when the pads need to be replaced. Pad wear sensors need to be replaced at the time of the brake service. To reduce brake squeal following a brake service, brake grease or anti-freeze compound is applied to the non-friction surface of the brake pads, pad ears, and slider bolts.
Almost all vehicles use disc brake systems, particularly on the front wheels. Disc brakes work by squeezing together a pair of brake pads on the rotating brake disc or rotor. The device that squeezes the pads together is called the brake caliper. Disc brakes can develop problems such as warped rotors - which cause the steering wheel to shake when the brakes are applied, or may become rusted and fail to apply or release evenly, causing uneven or accelerated brake pad wear.
Required Service or Repairs
Worn out brake pads limit your ability to safely slow and stop the vehicle. Brake pads should be replaced when the friction material reaches minimum acceptable levels. A thorough inspection of other brake components is essential to properly help avoid future brake problems. Ask about our brake inspection process. (713) 270-0474
How do brake pads work?
When the brake pedal is pressed, pressurized brake fluid forces the piston inside the brake caliper to move outwards. The brake calipers move on slider bolts so that even pressure is applied to the brake pads on both sides of the brake rotor.
The brake pads are comprised of a block of friction material fastened to a metal backing plate. Each time the brakes are used, a tiny amount of the friction material on the brake pads wears, varying widely depending on the design of the brake system and the driving conditions and style.
