Dorman - First Stop Brake Master Cylinder P/N:M630227
$71.99
Build the hydraulic pressure that pushes brake fluid to the wheel circuits with the Dorman First Stop Brake Master Cylinder M630227. When you press the pedal, this master cylinder converts that force into hydraulic pressure and feeds it through its two outlets to the brake system. It installs as a direct-fit replacement engineered to match the design, function, and performance of the original on the 1999-2004 Ford F-250, F-350, F-450 and F-550 Super Duty, the 2002 Ford E-550 Econoline Super Duty and 2003 E-550 Super Duty, and the 1999-2003 Ford F-53 Motorhome Chassis (all engines).
- 100% new: built entirely from new materials rather than remanufactured components.
- Aluminum housing: constructed to match the casting material of the original part for similar performance.
- EPDM seals: the rubber components use a high-quality EPDM compound that resists glycol-based brake fluid.
- SAE-spec build: made to meet rigorous SAE International standards.
This unit has a 1.375 in bore and two outlets, including a 7/16-24 rearward outlet, and ships with the reservoir and sensor included. Mounting hardware is not included — consult the vehicle service information for the correct fasteners and whether they may be reused. Country of origin: China.
