Build the hydraulic pressure your brakes depend on with the Dorman - First Stop Brake Master Cylinder M22975. This master cylinder converts brake-pedal force into the hydraulic pressure that actuates the vehicle's brakes, and it drops in as a direct-fit replacement for the 1957-1960 Ford F-100 and 1960-1966 Ford P-100 (All engines). It's precision-engineered to match the original master cylinder's design, function, and performance on the listed applications.

  • Cast-iron housing: constructed to match the casting material of the original part for similar performance.
  • EPDM rubber components: made from 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 SAE International standards.
  • Ready to plumb: includes a reservoir; a sensor is not included, and mounting hardware is not included.

It features a 1.063-inch bore and a single rearward outlet sized 1/2-20. Because mounting hardware is not included, consult the vehicle service information for the correct fasteners and whether they may be reused. Country of origin: Taiwan.
