The calliper assembly is an important component of the brake system in automobiles, typically consisting of a caliper body, piston(s), brake pads, brake lines, and seals.

During braking, when the brake pedal is depressed, hydraulic fluid from the brake master cylinder flows through the brake lines into the piston chamber of the brake caliper assembly, pushing the piston(s) and brake pads into contact with the brake disc or drum to generate braking force and slow down or stop the vehicle.

The main function of the brake caliper assembly is to produce braking force by pushing the brake pads through the piston(s) to slow down or stop the vehicle. Compared to traditional single-piston calipers, dual-piston and four-piston calipers are more common in high-performance cars and racing due to their ability to provide greater braking force and better braking performance.

The quality of the brake caliper assembly directly affects the safety and stability of the entire brake system, so it is important to choose and maintain high-quality products according to relevant requirements when selecting and replacing brake caliper assemblies.
