Wheel Cylinder Overhaul

DISASSEMBLY PROCEDURE





1. Remove the wheel cylinder from the vehicle.





2. Remove the wheel cylinder boots (4).
3. Remove the wheel cylinder pistons (3) and seals (2).
4. Remove the wheel cylinder spring assembly (5).
5. Remove the wheel cylinder bleeder valve (6).
6. Inspect the cylinder bore (1) and pistons (3) for the following conditions:
^ Scoring
^ Nicks
^ Corrosion
^ Wear
7. Use a crocus cloth in order to polish out light corrosion. Replace the wheel cylinder assembly if the bore does not clean up using the crocus cloth.
8. Clean all the parts in clean, denatured alcohol.
9. Dry the parts with unlubricated, compressed air.

CAUTION: When servicing brake parts, do not create dust by grinding or sanding brake linings, by cleaning brake parts with a dry brush or with compressed air. Many earlier models or aftermarket brake parts may contain asbestos fibers which can become airborne if dust is created during servicing. Breathing dust containing asbestos fibers may cause serious bodily harm. A water dampened cloth or water based solution should be used to remove any dust on brake parts. Equipment is commercially available to perform this washing function. These wet methods will prevent fibers from becoming airborne.

NOTICE: Brake fluid will damage painted surfaces. Shop cloths and clean containers should be used to prevent spillage of brake fluid.

10. Lubricate the new seals (2) with clean brake fluid.
