Front Brake Caliper

The front brake caliper has a single bore and is mounted to the steering knuckle with two caliper bolts. When the brakes are applied, hydraulic, pressure is exerted equally against the bottom of the piston and against the bottom of the cylinder bore. The pressure applied to the piston is transmitted to the inner pad forcing the pad against the inner rotor surface. The pressure applied to the bottom of the cylinder forces the caliper to slide in the caliper bolt bushings toward the center of the vehicle. This movement causes the outer section of the caliper to apply pressure against the back of the outer pad, forcing the pad against the outer rotor surface. As line pressure builds, the pads are pressed against the rotor surfaces with increased force, bringing the vehicle to a stop. The construction of the brake caliper and the movement of the piston seal automatically compensate for pad wear, the piston moves out in the housing bore when the brakes are applied. This outward movement of the piston distorts the seal. When the brake pedal is released, the piston returns only as far as the seal was distorted. This action makes up for pad wear, maintains the pad to rotor clearance, and also eliminates the need for brake adjustments.
