Rear
Rear Caliper:
The caliper assembly consists of a pin slider caliper housing with a single piston, parking brake mechanism, inner and outer pad/lining assemblies and an anchor plate. The caliper assembly has two lubricated locating pins that position the caliper relative to the anchor plate. Rubber slider pin boot seals prevent lubrication wash out and pin corrosion.
The piston has a moulded rubber dust boot on its outer end. The boot attaches to the cylinder bore and provides a seal between the housing and the piston. A rubber O-ring is positioned in a groove in the piston to provide a seal between the piston and housing. The components in the parking brake mechanism cavity in the back of the caliper housing are lubricated with silicone grease. An automatic adjuster in the piston moves on the push rod to compensate for lining wear and to maintain lining-to-rotor clearance (gap) when the brakes are not applied.
The parking brake cable is secured to the parking brake operating lever by a barrel crimp on the end of the cable. The parking brake cable is secured to the caliper by a retaining clip. When the parking brake is applied, the cable rotates the lever shaft. The push rod drives the piston and pad lining assembly against the rotor, creating the braking force.
