If your car is equipped with disc brakes, brake calipers are critical to slowing and stopping your car. Here's what you need to know.
The brake caliper plays a central role in a disc-brake system and has two functions. First, it acts either as a bracket to support the brake pads on either side of the rotor or to support the caliper bracket itself — there are other designs, but these are the two most common. Second, it uses pistons to convert pressure exerted on the brake fluid by the master cylinder into friction on the rotor.
In simple terms, a brake caliper’s purpose is to squeeze the brake pads against the rotor to stop the car. There are two main types of calipers, a single piston and a dual piston. Most front calipers are dual piston but many cars use single piston calipers on the rear, where less braking force is needed.
Stepping on the brake pedal forces the master cylinder piston forward, compressing the brake fluid. The brake fluid forces the brake caliper pistons toward the rotors, pinching the rotors in between the brake pads, which creates friction and slows the vehicle.
Regardless of the type of support, it is designed to have parts that withstand increased wear. The pads and discs we have not considered because they are considered consumables. As for the support, the return movement of the piston is provided by a rubber sleeve. When the driver depresses the brake pedal, the piston comes out of the body and deforms the brake sleeve kit, when the pedal is released, the cuff tends to present a starting position and drags the piston.
The brake system includes brake calipers, brake discs, brake pads(including brake pad fitting kits), steel pipes, brake fluid, etc. There are also brake rubber dust cover kits.
