$164.99
Convert brake-pedal effort into the hydraulic pressure that actuates the brakes with the Dorman - First Stop Brake Master Cylinder M630594. It drops in as a direct-fit replacement for the 2008-2009 Ford Taurus, 2008-2009 Ford Taurus X, 2009 Lincoln MKS, and 2008-2009 Mercury Sable, and is precision-engineered to match the original master cylinder's design, function, and performance on these applications.
- Aluminum housing: the cylinder housing is built to match the original part's casting material for similar performance.
- EPDM seals: all rubber components use a high-quality EPDM compound for resistance to glycol-based brake fluid.
- 100% new: made entirely of new materials, not remanufactured, and built to meet rigorous SAE International standards.
- Dual outlets: two outlets with a 1 in bore diameter and M14 x 1.5 outlet threads; the reservoir and sensor are included.
The master cylinder pressurizes brake fluid to the wheel circuits when you press the pedal. If a failing master cylinder is the cause of a sinking or spongy pedal or external fluid leakage, this unit replaces it — diagnose the cause first, since these signs can have other sources. Mounting hardware is not included; consult the vehicle service information for the correct fasteners and whether they may be reused. Country of origin: Taiwan.
