Disc Brakes

Floating caliper disc brake assembly uses a single piston caliper which "floats" on 2 bolts. As brake pedal is depressed, hydraulic pressure is passed through a proportioning valve to brake caliper piston.

This force is transmitted to inboard brake pad, forcing it against braking surface of rotor. Pressure then moves outer caliper housing and pad inward on caliper mounting bolts, thus forcing outer pad against outer braking surface of rotor.

When the brake is released, pressure is removed from the cylinders and inherent rotor runout moves pistons back into cylinders to maintain sufficient rotor-to-pad clearance.
