Description

Turn firm brake-pedal effort into the hydraulic pressure your brakes rely on with the Dorman - First Stop Brake Master Cylinder M39647. Precision-engineered to match the design, function, and performance of the original unit, it drops in as a direct-fit replacement for the 1988-1991 Chevrolet C1500 and 1988-1991 GMC C1500 (All engines).

Precise replacement: the aluminum cylinder housing is built to match the casting material of the original part for similar performance.
Durable design: all rubber components are made of a high-quality EPDM compound for resistance to glycol-based brake fluid.
100% new: made entirely of new materials, not remanufactured.
Strict specifications: made to meet rigorous SAE International standards.

This unit has two outlets, with a 1/2-20 rearward outlet size, and includes the reservoir. A sensor is not included, and mounting hardware is not included — consult the vehicle service information for the correct fasteners and whether they may be reused. Country of origin: China. If a worn or leaking master cylinder is behind a sinking or spongy pedal, this replaces it; diagnose the cause before ordering.

Frequently Asked Questions

What does a brake master cylinder do?

It converts the force from your brake pedal into hydraulic pressure that is sent to the brakes, so it is the heart of the hydraulic braking system.

What vehicles does the M39647 fit?

It is a direct-fit replacement for the 1988-1991 Chevrolet C1500 and 1988-1991 GMC C1500 (All engines). Check the Buyer's Guide tab to confirm your vehicle.

Does this master cylinder include a reservoir?

Yes. The reservoir is included. A sensor is not included, and the package contents are the master cylinder itself.

Is mounting hardware included?

No, mounting hardware is not included. Consult the vehicle service information for the correct fasteners and whether they may be reused.

What are signs my master cylinder may need replacing?

A pedal that slowly sinks, feels spongy, or brake fluid leaking near the cylinder can signal a failing master cylinder. Diagnose the cause before replacing, as other parts can cause these signs.
