Master Cylinder: Inspection
- Wash master cylinder body, bore and piston assemblies with denatured or isopropyl alcohol. Inspect piston assemblies and return springs. Replace pistons if scored, worn, cracked or broken. Replace springs if broken, bent, collapsed, distorted or fatigued.
- Inspect cylinder bore for scoring, corrosion or wear. Aluminum body of master cylinder is anodized. Some wear on anodized surface, as evidenced by lighter areas, is normal. Aluminum master cylinders may not be polished, but must be replaced.
