Turn pedal effort into hydraulic brake pressure with the Dorman First Stop Brake Master Cylinder M39575, a direct-fit replacement for all engines on the 1984-1992 Chevrolet Camaro and 1984-1992 Pontiac Firebird. Dorman designed it to match the original master cylinder's design, function and performance. It is built from new, high-quality materials to serve as a safe, durable replacement.
- Precise replacement: the cast iron cylinder housing matches the casting material of the original part and is intended to deliver similar performance.
- Durable design: every rubber component uses a high-quality EPDM compound that resists glycol-based brake fluid.
- 100% new: made entirely of new materials for quality and safety.
- Strict specifications: built to meet rigorous SAE International standards.
The master cylinder has two outlets and comes with its reservoir. Mounting hardware and a sensor are not included, so consult the vehicle service information for the correct fasteners and whether the originals may be reused. The package contains one master cylinder. Country of origin: China.
Common signs a master cylinder may need replacing include a brake pedal that slowly sinks under steady pressure, a soft or spongy pedal, or brake fluid seeping from the unit. Other brake components can cause these symptoms, so diagnose the system before replacing parts, and bleed the brakes as the service procedure directs after installation.
