Service your rear drum brakes with this Dorman drum brake wheel cylinder, part number W370031 from the Dorman - First Stop line. It pushes the brake shoes against the drum when you press the pedal. It fits many vehicles, among them the 1995-1997 Ford Ranger, 1995-1997 Mazda B2300 and 1995-1997 Mazda B3000. It is cataloged for the rear position, left and right. See the Buyer's Guide tab for the full list and engine details.
Inside the drum, the wheel cylinder takes hydraulic pressure from the brake system and pushes the brake shoes outward against the drum. Dorman engineered this unit as a direct replacement, designed to match the original wheel cylinder in fit, function and performance on the listed applications. It is manufactured and tested for quality assurance.
- Ideal replacement: Built as a direct match for the original drum brake wheel cylinder on the listed applications.
- Cost-effective service step: Dorman recommends replacing the cylinder while the drum brakes are already apart for service.
- Quality materials: Uses EPDM rubber cups and boots.
- Professionally tested: The wheel cylinder bores are surface-tested so the pressure cups have a proper sealing surface.
Signs a wheel cylinder may need replacing include brake fluid seeping at the backing plate, fluid-soaked brake shoes, a soft or sinking pedal, or the vehicle pulling during braking. Diagnose the cause before replacing parts.
