Description

Restore firm, reliable hydraulic braking with the Dorman - First Stop Brake Master Cylinder M630337. This master cylinder converts brake-pedal force into the hydraulic pressure that pushes fluid through the wheel circuits, and it drops in as a direct-fit replacement for the 2003-2006 Ford Expedition [All] and 2003-2006 Lincoln Navigator [All]. If a worn or leaking original cylinder is the cause of a sinking or spongy pedal, this unit replaces it.

100% new: Built entirely from new materials, not remanufactured.
Aluminum housing: The cylinder housing is constructed to match the casting material of the original part for similar performance.
EPDM rubber components: Made of a high-quality EPDM compound for resistance to glycol-based brake fluid.
Built to spec: Made to meet rigorous SAE International standards.

It has a 1.125 in bore and two outlets — a rearward M14 x 1.5 and a secondary M12 x 1.0 thread (1 mm primary thread pitch). The reservoir and sensor are included. Mounting hardware is not included; consult the vehicle service information for the correct fasteners and whether they may be reused. Country of origin: Taiwan.
