Master Cylinder Assembly Inspection

Inspection
Inspect all disassembled parts for wear or damage, and replace parts if necessary.

NOTE:
^ Wash disassembled parts with brake fluid.
^ Do not reuse piston cups and cylinder cup.

Inspect master cylinder bore for scoring or corrosion. It is best to replace corroded cylinder. Corrosion can be identified as pits or excessive roughness.

NOTE: Polishing bore of master cylinder with cast aluminum body with anything abrasive is prohibited, as damage to cylinder bore may occur.

Rinse cylinder in clean brake fluid. Shake excess rinsing fluid from cylinder. Do not use a cloth to dry cylinder, as lint from cloth cannot be kept from cylinder bore surfaces.
