Every stop starts here: the new Dorman First Stop Brake Master Cylinder M39376 converts the force on your brake pedal into the hydraulic pressure that applies the brakes. It is a direct-fit replacement for many vehicles, among them the 1983 Chevrolet Malibu, 1983-1988 Chevrolet Monte Carlo and 1983-1987 Chevrolet El Camino; see the "Vehicles it fits" section for the full list. It is precision-engineered to match the original master cylinder's design, function and performance on those vehicles, and it is made of new, high-quality materials.
- Precise replacement: the cast-iron cylinder housing is built to match the casting material of the original part, so it is intended to deliver similar performance.
- Durable design: all rubber components use a high-quality EPDM compound that resists glycol-based brake fluid.
- 100% new: made entirely from new materials for quality and safety.
- Strict specifications: built to meet rigorous SAE International standards.
Specifications: 2 outlets; rearward outlet size 1/2-20. The reservoir is included. No sensor or mounting hardware is included, so consult the vehicle service information for the correct fasteners and whether they may be reused. Country of origin: China.
Signs a master cylinder may need replacing include a soft or sinking brake pedal, brake fluid leaking at the master cylinder, and a falling reservoir level. Diagnose the brake system before replacing parts, because other hydraulic components can cause similar symptoms.

Frequently Asked Questions
What does the brake master cylinder do?
It converts brake pedal force into hydraulic pressure. It then sends brake fluid through its two outlets into the brake lines, which carry it to the wheel brakes.
Is the reservoir included with M39376?
Yes, the reservoir is included. A sensor and mounting hardware are not, so consult the vehicle service information for the correct fasteners and whether they may be reused.
Which vehicles does this master cylinder fit?
It fits many vehicles, among them the 1983 Chevrolet Malibu, 1983-1988 Chevrolet Monte Carlo and 1983-1987 Chevrolet El Camino. See the "Vehicles it fits" section for the full list.
What is the master cylinder made of?
The cylinder housing is cast iron, built to match the casting material of the original part. All rubber components use an EPDM compound that resists glycol-based brake fluid.
What are signs a master cylinder may need replacing?
A soft or sinking pedal, fluid leaking at the master cylinder, or a falling reservoir level can be signs it may need replacing. Diagnose the system first, as other hydraulic parts can cause similar symptoms.
