Keep your rear drum brakes applying steady hydraulic pressure with the Dorman - First Stop Drum Brake Wheel Cylinder W37640, a rear wheel cylinder that drops in on the 1984-1986 Ford Bronco II, the 1984-1986 Ford Ranger, the 1990-1994 Ford Ranger, and the 1994-1996 Mazda B2300, B3000 and B4000 (All engines). It converts hydraulic pressure from the brake line into outward force, pushing the drum brake shoes against the drum to slow the wheel. Engineered as a direct replacement, it is built and tested to match the fit, function and performance of the original cylinder on the listed applications.
- Cast iron body: with a 0.813 in bore, surface-tested to give the pressure cups an optimum sealing surface.
- EPDM rubber cups and boots: high-quality rubber components for long-lasting performance.
- M10 x 1.0 inlet thread: 10 mm thread diameter, 1.0 pitch.
- Bleeder screw included: a bleeder screw cap is not included.
Replacing the wheel cylinder while servicing the drum brakes is a fast, cost-effective way to keep the hydraulic side working. The listed applications use two per rear axle; sold individually, so order 2 to do both sides together as a matched pair for balanced braking. Country of origin: China.
