Dorman - First Stop Brake Master Cylinder P/N:M39876
$111.99
The Dorman - First Stop Brake Master Cylinder (MPN M39876) develops the hydraulic pressure a master cylinder sends to the brake circuits each time you press the pedal, and it drops in as a direct-fit replacement for the 1988-1997 Ford F-Super Duty, 1989-1997 Ford F-53 Motorhome Chassis, 1989-1996 Ford F-59 Commercial Stripped Chassis, and 1994-1997 Ford F-350 (all engines).
- Aluminum housing: the cylinder housing is built to match the casting material of the original part for comparable performance.
- 100% new: made entirely of new materials, not remanufactured, and built to meet rigorous SAE International standards.
- Fluid-resistant seals: all rubber components use a high-quality EPDM compound for resistance to glycol-based brake fluid.
- What's in the box: ships as a master cylinder with the reservoir and sensor included, featuring two outlets, a 1.313 in bore diameter, and a 7/16-24 secondary outlet thread diameter. Mounting hardware is not included — consult the vehicle service information for the correct fasteners and whether they may be reused.
A worn or failing master cylinder can show up as a spongy or slowly sinking brake pedal or a loss of brake fluid; if a faulty master cylinder is the cause, this unit replaces it, but diagnose the cause before replacing. Country of origin: China.
