Frequently Asked Questions

What does this brake master cylinder do?

It converts the force from your brake pedal into hydraulic pressure, sending fluid out through its two outlets to the brake circuits. If a failed master cylinder is the cause of your brake issue, this replaces it.

Does it include a reservoir, sensor, or mounting hardware?

The reservoir is included. 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.

What vehicles does the M64885 fit?

It is a direct-fit replacement for a range of 1967-1978 Chevrolet and GMC full-size cars, pickups, Suburbans and vans (engine: All). See the Buyer's Guide tab for the complete application list.

What are the key specifications?

It has a cast-iron housing, two outlets, a 1-inch bore, and a 1/2-20 secondary outlet thread. Its rubber components use a high-quality EPDM compound that resists glycol-based brake fluid.

What are signs the master cylinder may need replacing?

Signs may include a brake pedal that slowly sinks or feels spongy, or brake fluid leaking at the cylinder. Diagnose the cause before replacing, as these symptoms can have other sources.
