The Dorman drum brake wheel cylinder W37333 uses hydraulic brake pressure to push the brake shoes outward against the drum, and it installs as a direct-fit replacement for the 1972-1975 Ford F-100 (All engines). Replacing the wheel cylinder while you service the drum brakes is a fast, cost-effective way to keep the hydraulic side of the brake working properly.

  • Cast iron body: machined for durability and a stable sealing bore.
  • EPDM rubber cups and boots: high-quality seals designed for long-lasting performance.
  • Surface-tested bore: the 1.063 in. cylinder bore is surface-tested to provide an optimum sealing surface for the pressure cups; 3/8-24 inlet thread.
  • Bleeder screw included (bleeder screw cap not included).

Designed as a direct replacement that reproduces the original wheel cylinder's function on these applications, and manufactured and tested for quality assurance. Cataloged for the front-left, front-right and rear-right positions on the listed applications. Country of origin: China.
