Brake Master Cylinder: Service and Repair
Overhaul
Disassembly Procedure
DISASSEMBLY PROCEDURE
NOTICE: Do not hone the master cylinder bore. When the brake master cylinder is overhauled, it is recommended that the cylinder body be
replaced rather than CLEANED UP by honing the bore. The master cylinder has a hard, highly polished BEARINGIZED surface, which is
produced by diamond boring followed by ball or roller burnishing under heavy pressure. Honing will destroy this hard smooth surface and cause
rapid wear of the rubber cups.
1. Unscrew the cap.
2. Remove the diaphragm.
3. Drain the brake fluid from the reservoir.
4. Remove the reservoir and two grommets from the master cylinder body.
5. Clamp the master cylinder mounting flange in a vise. Pry the reservoir off with a bar.
6. Remove the snap ring.
