The Dorman - First Stop Brake Master Cylinder M630001 is the part that turns pedal effort into hydraulic pressure for the brakes at every wheel. It is a direct-fit replacement for the 2004-2008 Ford F-150, the 2004-2006 Ford Lobo and the 2006-2008 Lincoln Mark LT. See the Buyer's Guide tab for engine details.
This Dorman brake master cylinder is precision-engineered to mirror the original unit's design, function and performance on the listed trucks. It is built from new, high-quality materials for a safe, durable replacement.
- Precise replacement: The cylinder housing is constructed to match the casting material of the original part and is designed to deliver similar performance.
- Durable design: Every rubber component uses a high-quality EPDM compound that resists glycol-based brake fluid.
- 100% new: Made entirely from new materials.
- Strict specifications: Made to meet rigorous SAE International standards.
Signs a master cylinder may need replacing include a soft or spongy pedal, a pedal that slowly sinks under steady pressure, a dropping fluid level, and fluid seeping from the cylinder. If a worn master cylinder is causing the problem, this unit replaces it. Other brake faults can produce similar symptoms, so diagnose the cause before ordering. Bench-bleed the new cylinder and bleed the brake system as the vehicle service information directs.
