Detailed Description

This brake master cylinder is engineered for classic Chevrolet Corvette brake hydraulic service where front disc brakes are present. The 1-inch bore supports proper hydraulic pressure for the system, while the integral reservoir and cast iron housing match the needs of a durable replacement master cylinder. NM1371 is a new unit with no brake booster, push rod, gasket, seal, or mounting hardware included, so existing vehicle-specific components should be verified before installation. This part cross-references 5455509 and 5458833 for the same application.

What It Helps Fix

• External brake fluid leakage from a worn master cylinder

Installation Notes and Tips

Confirm the vehicle is a 1967-1969 Chevrolet Corvette with front disc brakes before ordering. Bench bleed the master cylinder before final installation, use fresh DOT 3 brake fluid, and inspect the brake lines, booster interface, and mounting surfaces for wear or contamination. Because mounting hardware is not included, reuse or source the correct fasteners as needed.
