Dorman - First Stop Brake Master Cylinder P/N:M630525
$154.99
Convert brake-pedal force into the hydraulic pressure that feeds both brake circuits with the Dorman - First Stop Brake Master Cylinder M630525. It drops in as a direct-fit replacement for the 2006-2010 Ford Explorer [All], 2007-2010 Ford Explorer Sport Trac [All], and 2006-2010 Mercury Mountaineer [All], and is precision-engineered to match the design, function, and performance of the original master cylinder on these applications.
- 100% new: built entirely from new, high-quality materials — not remanufactured.
- Cast aluminum housing: constructed to match the casting material of the original part for similar performance, with a 1.063 in bore and two outlets (M12 x 1.0 thread).
- EPDM rubber components: chosen for resistance to glycol-based brake fluid.
- SAE standards: made to meet rigorous SAE International standards; includes the reservoir and sensor.
Signs the original master cylinder may need replacing include a pedal that slowly sinks under steady foot pressure, a low or spongy pedal, or internal fluid loss. If a failed master cylinder is the cause, this unit replaces it; diagnose the cause first, as other brake components can produce similar symptoms. Mounting hardware is not included — consult the vehicle service information for the correct fasteners and whether they may be reused. Country of origin: Taiwan.
