The brake caliper piston is important because it makes sure that the brake pads come into contact with the brake discs. The caliper pistons are in charge of forcing the brake pads against the brake rotor to bring the vehicle to a halt.
Brake caliper piston operationThe brake caliper functions by using single pistons, dual, 4, or 6 piston calipers. The design of the single pistons allows the caliper to center when applying pressure on the brake, so the brake pads have equal force. Dual, 4, or 6 piston calipers deal with the hydraulic force generated from both sides of the caliper. And brake fluid flows through the caliper when applying pressure on the brake pedal.
Piston MaterialBrake caliper pistons can be composed of various materials, like aluminum and steel. Both have their pros and cons aluminum pistons are known to be lightweight but susceptible to corrosion. While steel pistons are considered to be very strong and secure but suffer the same fate of being vulnerable to corrosion.
Common issues with a faulty brake caliper pistonA faulty brake caliper piston can cause the vehicle to pull when steering, make loud noises, and the brake pads will wear out unevenly.
