The Dorman - First Stop Brake Master Cylinder M56193 converts brake-pedal effort into the hydraulic pressure that operates the braking system, and it drops in as a direct-fit replacement for a wide range of classic AMC and Jeep vehicles — including the 1963-1972 AMC Ambassador, 1970-1976 AMC Gremlin and Hornet, 1970-1975 Jeep CJ5 and CJ6, and 1966-1973 Jeep Wagoneer. See the Buyer's Guide tab for the full list of 26 applications.

Engineered to match the design, function, and performance of the original master cylinder on the listed applications, its cast-iron housing is built to match the casting material of the original part for similar performance.

  • 100% new: made entirely of new materials, not remanufactured.
  • Fluid-resistant seals: rubber components use a high-quality EPDM compound for resistance to glycol-based brake fluid.
  • Cast-iron housing: constructed to match the casting material of the original part.
  • Built to spec: made to meet rigorous SAE International standards.

It features a 1 in bore diameter and two outlets, with a 1/2-20 secondary (rearward) outlet thread. The reservoir is included; a sensor and mounting hardware are not. Consult the vehicle service information for the correct fasteners and whether they may be reused. If a failed master cylinder is the cause of a sinking or spongy brake pedal, this replaces it. Country of origin: China.

Interchange: Manufacturer part number M56193.
