Brake Master Cylinder: Testing and Inspection

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

NOTE: Wash disassembled parts with brake fluid and do not reuse piston cups.

^ Inspect master cylinder bore for scoring or corrosion. It is best to replace corroded cylinder. Corrosion can be identified as pits or excessive roughness.
Check for a cracked master cylinder casting or brake fluid around the master cylinder. Leaks are indicated only if there is at least a drop of fluid. A damp condition is not abnormal.

NOTE: Polishing bore or 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.
