Cleaning and Inspection

1. Disassemble master cylinder.
2. Wash brake master cylinder body.

NOTE: The aluminum body of the brake master cylinder is anodized. Some signs of bore wear on the anodized surface, as evidenced by lighter areas of the anodized surface, are normal and not detrimental.

CAUTION: Honing of the bore on aluminum brake master cylinder is not recommended as the anodic coating and hardness could be removed.

3. Inspect seals on primary and secondary piston assemblies for cuts, nicks, scratches or signs of wear, and for presence of any blistering or swelling.
4. Inspect master cylinder bore for pitting, corrosion or heavy wear. Heavy wear is characterized by corrosion or rusting of metal.
