Keep hydraulic pressure flowing from the pedal to the wheels with the Dorman First Stop Brake Master Cylinder, part number M630823. It is a direct-fit replacement for the 1967-1969 Chevrolet C50 with all engines. It is built from all-new materials and engineered to mirror the original master cylinder's design, function and performance.
The master cylinder converts force from the brake pedal into hydraulic pressure and sends it through the brake lines. If a worn or leaking original is causing a soft or sinking pedal, fluid seeping around the unit, or a reservoir that keeps losing fluid, this new cylinder replaces it.
- Precise replacement: the cast iron cylinder housing is built to match the casting material of the original part, for similar performance.
- Durable design: every rubber component is made from a high-quality EPDM compound that resists glycol-based brake fluid.
- 100% new: made entirely from new materials, with a focus on quality and safety.
- Strict specifications: made to meet rigorous SAE International standards.
Specifications: 23 mm bore diameter · 1/2-20 rearward outlet size · reservoir included · sensor not included · mounting hardware not included. Country of origin: China.
Consult the vehicle service information for the bleeding procedure, the correct mounting fasteners, and whether the original fasteners may be reused.
