FAQ for Other Repair Info

Q: How do I install the Duo-Servo Drum Brakes?
A:
You should install the Wheel Cylinder, the bolts, the brake pip, and the linings.
Q: How do I install the Vacuum Brake Booster Hose?
A:
You should route the hose in the same position as it was before removal, install the hose to the fitting on the engine and install the hose to the fitting on the Brake Booster.
Q: What should be cautioned in disassembling Master Cylinder?
A:
You can 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 to the rubber cups.
