Dorman - First Stop Brake Master Cylinder P/N:M39639

Turn pedal pressure into the hydraulic force that operates the brakes with the Dorman - First Stop Brake Master Cylinder M39639. It installs as a direct-fit replacement for the 1982-1989 Dodge Colt [All], 1982 Plymouth Champ [All], 1983-1989 Plymouth Colt [All], 1985-1988 Mitsubishi Mirage [All], 1986-1989 Hyundai Excel [All], and 1987-1989 Mitsubishi Precis [All], and is precision-engineered to match the design, function, and performance of the original unit on those applications.

• 100% new: made entirely from new materials, not remanufactured.
• Aluminum housing: cast to match the original part's casting material for similar performance.
• Durable EPDM rubber components: chosen for resistance to glycol-based brake fluid.
• Two outlets: M10 x 1.0 threads (1 mm pitch), with a 0.813 in bore diameter.
• Reservoir and sensor included; mounting hardware is not included.

The master cylinder converts brake-pedal effort into hydraulic pressure and distributes it through its two outlets to the brake circuits; if a leaking or failing master cylinder is the cause of a sinking pedal or lost braking, this replaces it. Made to meet rigorous SAE International standards. Because mounting hardware is not included, consult the vehicle service information for the correct fasteners and whether they may be reused. Country of origin: China.

Manufacturer part number M39639.
