Keep firm hydraulic pressure flowing to your rear drum brakes with the Dorman - First Stop Drum Brake Wheel Cylinder (W610131). It installs as a direct-fit rear wheel cylinder for the 2002-2003 Chevrolet Silverado 2500, 2004 Chevrolet Silverado 3500, 2005-2008 Chevrolet Silverado 1500 and GMC Sierra 1500, plus the 2007 Chevrolet Silverado 1500 Classic and GMC Sierra 1500 Classic (All engines).
Mounted on the rear backing plate, the wheel cylinder uses brake-line pressure to push its internal pistons outward, spreading the brake shoes against the drum when you press the pedal. Dorman engineered this unit to match the original wheel cylinder's fit and function on the listed applications, and it is manufactured and tested for quality.
- Cast-iron body: houses a 0.938 in bore with an M10 x 1.0 inlet thread.
- High-quality EPDM rubber cups and boots: for long-lasting sealing performance.
- Surface-tested bores: checked to provide an optimum sealing surface for the pressure cups.
- Bleeder screw included (bleeder screw cap not included).
Sold individually; the listed applications use two, so order 2 to service both sides. Replacing the wheel cylinders while servicing the drum brakes is a cost-effective way to help maintain braking performance. Country of origin: China.
