Rear Brake Caliper (Part 2 Of 2):

The rear calipers (2552) are hydraulically activated, pin slider-type assemblies with integral mechanically (cable) operated parking brake mechanisms. The rear disc brake caliper Assembly consists of:
^ A pin slider caliper housing with a single rear disc brake piston and adjuster (2B588) and parking brake mechanism.
^ inner and outer rear brake shoes and linings (2200).
^ rear disc support bracket (2B511).
^ two lubricated disc brake caliper locating pins (2B296) that position the rear disc brake caliper relative to the rear disc support bracket.
^ rubber slider pin boot seals which prevent lubrication wash out and pin corrosion.
^ A single brake shoe hold-down spring (2068) is mounted on the top of the rear disc brake caliper (2552) applying spring tension on the rear brake shoe and lining (2200).
