Dorman - First Stop Drum Brake Wheel Cylinder P/N:W610003
Dorman W610064 rear left drum brake wheel cylinder for the 1995-1998 Chevrolet W3500 Tiltmaster and other vehicles turns hydraulic pressure into force that pushes the brake shoes against the drum. This Dorman drum brake wheel cylinder is engineered as a direct match for the original wheel cylinder on particular vehicles, and it is manufactured and tested for quality assurance.
Fluid on the rubber boot or inside the drum, a soft pedal or pulling to one side can mean a wheel cylinder is leaking. These signs alone do not prove this part is the problem; air in the brake lines can also give a soft pedal. This listing is one rear left wheel cylinder, and the right side is a separate part, so both sides are normally replaced together.
It is listed for a wide range of Chevrolet, GMC and Isuzu models, including the 1995-1998 GMC W3500 Forward and the 1993-1998 Isuzu NPR. The rear left side of the 1995-1998 Chevrolet W3500 Tiltmaster takes two, and the right side is ordered separately.
