Rear Brake Caliper

The rear disc brake caliper has a single piston in an aluminum housing which is suspended in the anchor bracket on two guide pins. Hydraulic pressure, created by applying force to the brake pedal, acts equally against the piston and the bottom of the caliper bore to move the piston outward and to slide the caliper inward resulting in a clamping action on the rotor. This clamping action forces the pads against the rotor creating friction to stop the vehicle. When the parking brake is applied, the lever on the caliper causes the pushrod, the actuating collar and the clamp rod to be moved outward and the caliper to slide inward, mechanically forcing the pads against the rotor. Parking brake application is completely independent of the hydraulic braking system.
