Rebuild a leaking rear drum brake wheel cylinder and help restore proper hydraulic sealing with the Dorman First Stop Drum Brake Wheel Cylinder Kit (MPN 46348). Its components are designed to match the original wheel cylinder parts on the listed applications, so the rebuilt cylinder can seal like the factory unit when a worn or leaking wheel cylinder is the cause. It's a direct-fit repair kit for the rear drum brakes on a wide range of classic domestic cars, trucks, and vans built between 1964 and 2002, including the 1971-1973 Buick Centurion, 1973-1977 Buick Century, and 1975-1981 Chevrolet Camaro — see the Buyer's Guide tab for the full list of makes, models, and years.
- Includes boots, cups, and seals: supplies the dust boots, wheel cylinder cups, and seals needed to rebuild the wheel cylinder.
- Not included: wheel cylinder pistons, expander spring, bleeder screw, bleeder screw cap, and mounting hardware are not part of this kit.
- 0.938 in. bore: built for a 0.938-inch wheel cylinder bore.
- Quality components: made from quality components for dependable performance and a long service life.
Each listed application uses two rear wheel cylinders, so plan on two of these kits per vehicle. Country of origin: China. Signs the wheel cylinder may need rebuilding include brake fluid seeping at the wheel, fluid on the drum or shoes, and a low or spongy pedal — diagnose the cause before replacing.
