Dorman - First Stop Brake Master Cylinder P/N:M630258

Convert brake-pedal force into the hydraulic pressure your brakes rely on with the Dorman First Stop Brake Master Cylinder M630258 — a direct-fit replacement for the 1999-2003 Ford Windstar (All engines). It's precision-engineered to match the original master cylinder's design, function, and performance on this application, so the pedal feel and hydraulic output stay true to the factory unit.

• 100% new: built entirely of new materials, not remanufactured.
• Aluminum housing: constructed to match the casting material of the original part for similar performance.
• Durable rubber: all rubber components use a high-quality EPDM compound to resist glycol-based brake fluid.
• Two outlets: both sized M12 x 1.0 with a 1 mm thread pitch, feeding a 1.063 in bore.

This unit ships with the reservoir and sensor included, and is made to meet SAE International standards. Mounting hardware is not included — consult the vehicle service information for the correct fasteners and whether they may be reused. If a failed master cylinder is behind a sinking pedal, spongy feel, or fluid loss, this replaces it. Country of origin: China.
