Rebuild a leaking drum brake wheel cylinder with the Dorman First Stop Drum Brake Wheel Cylinder Kit (MPN 11304). It fits a wide range of medium- and heavy-duty trucks, including the 1958-1959 GMC 370, 1970-1972 Ford F-600, 1979-1983 Chevrolet P40, and 1980-1985 Chevrolet C60/C70 — see the Buyer's Guide tab for the full list of applications. Per the catalog, this kit services wheel cylinders in front and rear positions (front upper, front lower, and rear upper) on the listed vehicles.
A drum brake wheel cylinder uses hydraulic pressure to push its pistons outward against the brake shoes; the cups and dust boots seal the bore and help keep out contamination. If leaking cups or torn boots at the wheel cylinder are the cause of fluid seepage, a soft pedal, or brake fluid on the shoes, this kit rebuilds them.
- Kit contents: includes wheel cylinder cups (seals) and dust boots, sized to a 1.125 in bore.
- Not included: wheel cylinder pistons, the expander spring, bleeder screw and bleeder screw cap, and mounting hardware are not included.
- Designed to match: the components are made to match the original parts needed to rebuild the wheel cylinder on the specified vehicles.
- Durable build: made from quality components for reliable performance and long service life, backed by a team of product experts in the United States with over a century of automotive experience.
