Rear brake caliper pistons are an essential component of any vehicle's braking system. These small but mighty parts are responsible for applying pressure to the brake pads, which in turn slows down or stops the vehicle. Made from high-quality materials such as steel or aluminum, rear brake caliper pistons are designed to withstand the intense heat and pressure generated by the braking process. They come in a range of sizes and shapes to fit different types of vehicles and can be easily replaced when they become worn or damaged. For optimal safety and performance, it is recommended to use only genuine rear brake caliper pistons that are specifically designed for the make and model of your vehicle.

Frequently Asked Questions (FAQs)

1. Do rear brakes have pistons?

Cars with rear disc brakes have self-adjusting pistons that move in and out when the parking brake is applied. These pistons usually screw in and out, so need to be turned to make them retract for pad replacement.

2. Can you replace a brake caliper piston?

Often the whole brake caliper assembly is replaced when this happens but that is a real shame: They are very simple things, and for about 20 USD you can buy a brake caliper repair kit (which can include a brand new piston) and with an hour or so of work, your caliper will be as good as new!
