Turn brake-pedal force into the hydraulic pressure your braking system needs with the Dorman - First Stop Brake Master Cylinder M36208. It installs as a direct-fit replacement for the 1966 Ford Fairlane, 1966 Ford Falcon, 1966 Mercury Comet, and 1966 Mercury Cyclone.
A master cylinder that no longer holds pressure often shows up as a brake pedal that slowly drops toward the floor or feels soft even after bleeding. Because those symptoms can also come from other parts of the hydraulic system, diagnose the cause before replacing. If a failed master cylinder is the source, this M36208 restores the pedal-to-hydraulic function. Bleed the brakes and confirm firm pedal feel after installation.
