Wheel Cylinder: Testing and Inspection

NOTE: A slight amount of fluid is normally present and acts as a lubricant for the rear wheel cylinder. Removal is not necessary to disassemble, inspect, and overhaul the rear wheel cylinder. Removal is necessary for replacement only.

^ Rear wheel cylinders should not be disassembled unless they are leaking. Pull back each rear wheel cylinder dust boot as shown and inspect for leakage.
^ When inspecting a wheel cylinder, excessive fluid indicates leakage past the piston cups and a need to overhaul the wheel cylinder. A slight amount of fluid is normally present and acts as a lubricant for the pistons. If evidence of leakage is noted, the wheel cylinder should be disassembled, overhauled, or replaced.
^ Inspect the rear wheel cylinder bore for scratches and pitting. If the rear wheel cylinder is pitted or has deep scratches, the rear wheel cylinder must be replaced.
