Honda CB Brake Master Cylinders & Rebuild Kits

Honda CB Brake Master Cylinders and Rebuild Parts

The brake master cylinder converts movement at the lever or pedal into hydraulic pressure for the brake caliper. Worn internal seals, damaged reservoir components, corrosion or fluid leakage can cause inconsistent operation or loss of pressure. Because the master cylinder is part of a safety-critical system, leaks, sticking components and unreliable brake feel should be inspected and corrected before the motorcycle is ridden.

This collection includes complete front and rear master-cylinder assemblies, internal rebuild kits, piston components, reservoirs, caps, diaphragms, rubber boots, dampers, banjo bolts and sealing washers. Honda CB master cylinders vary by model, year and brake configuration. Bore diameter, mounting design, lever arrangement, hose connection and rebuild-kit dimensions must match the installed system. The cylinder bore should also be inspected because severe corrosion or damage may prevent a rebuild kit from producing a reliable repair.

Complete your hydraulic brake service with the appropriate brake caliper rebuild parts and brake pads, shoes and hoses. Bleeding and inspection equipment is available under brake, tire and wheel tools. Use the My Motorcycle selector to display master cylinders and rebuild parts listed for your Honda CB model and year.
