Dorman - First Stop Brake Master Cylinder P/N:M630277

Build firm hydraulic pressure to every wheel with the Dorman - First Stop Brake Master Cylinder (M630277), a direct-fit replacement for the 1999-2000 Ford F-53 Motorhome Chassis [All] and the 1999-2001 Freightliner FL50, FL60, FL70 and FL80 [All]. As the master cylinder, it converts brake-pedal force into the hydraulic pressure that operates the vehicle's brakes. Signs the original may need replacing include a sinking or spongy pedal, internal or external fluid leaks, and reduced braking response.

• Cast-iron housing: the cylinder housing is built to match the casting material of the original part for similar performance.
• Two outlets: features 2 outlets, with a 1/2-20 secondary outlet thread diameter, and a 2-inch bore.
• EPDM rubber components: 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.

Includes the reservoir. A sensor and mounting hardware are not included; consult the vehicle service information for the correct fasteners and whether they may be reused. Country of origin: China.
