Mechanical output force is applied from the hydraulic brake caliper pistons to the inner brake pads. As the pistons press the inner brake pads outward, the caliper housings draw the outer brake pads inward. This allows the output force to be equally distributed. The brake pads apply the output force to the friction surfaces on both sides of the brake rotors, which slows the rotation of the tire and wheel assemblies. The correct function of both the brake pad and brake caliper hardware is essential for even distribution of braking force.

J64:

Mechanical output force is applied from the hydraulic brake caliper 4 pistons, two pistons on each side of the caliper. They are connected hydraulically by a brake pipe. The hydraulic pressure press the brake pads outwards. The brake pads apply the output force to the friction surface on both sides of the rotors, which slows the rotation of tire and wheel assemblies. The correct function of both the brake pad and brake caliper hardware is essential for even distribution of braking force.
