Keep your rear drum brakes applying with firm, even hydraulic pressure using the Dorman - First Stop Drum Brake Wheel Cylinder (P/N W37236). This rear wheel cylinder drops in as a direct-fit replacement across a range of classic Chrysler, Dodge, and Plymouth applications, including the 1968-1969 Chrysler Imperial, the 1975-1977 Dodge B100, the 1967-1968 Dodge Monaco, and the 1967-1968 Dodge Polara — see the Buyer's Guide tab for the full list of 14 applications.
When you press the brake pedal, fluid enters the cylinder and drives its pistons outward, pushing the brake shoes against the drum to create braking friction. Over time, seals can weaken and let fluid seep past the pistons.
- Rear drum position: cataloged for the rear axle drum brakes on the listed vehicles.
- Hydraulic actuation: converts brake-fluid pressure into outward piston travel to apply the shoes.
- Direct-fit replacement: engineered to install on the listed classic Chrysler, Dodge, and Plymouth applications.
Signs a wheel cylinder may need replacing include fluid weeping behind the drum, a soft or sinking pedal, or pistons that stick. If a failed wheel cylinder is the cause, this replaces it.
