Turn brake-line hydraulic pressure into the force that pushes your drum brake shoes outward against the drum with the Dorman - First Stop Drum Brake Wheel Cylinder W610179. It's a direct-fit replacement for the 2004-2009 Chevrolet W3500 Tiltmaster, 2004-2008 GMC W3500 Forward, 2004-2009 and 2011-2015 Isuzu NPR, and 2011-2015 Isuzu Reach [All]. Engineered to drop in like the original wheel cylinder on the listed applications, it is manufactured and tested for quality assurance. This is the rear left forward wheel cylinder for those trucks.

  • Cast iron body: the bore is surface-tested to provide an optimum sealing surface for the pressure cups.
  • EPDM rubber cups and boots: made with high-quality EPDM rubber sealing components.
  • Bleeder screw included: a bleeder screw is included; a bleeder screw cap is not included.
  • Fit specs: 1.063 in inside diameter with an M10 x 1.0 brake-line inlet thread.

Replacing the wheel cylinder while servicing the drum brakes is a fast, sure way to keep the drum-brake hydraulics sealed. Signs the original may need replacing include brake fluid weeping past the cups or boots, a soft or sinking pedal, or contaminated shoes; if a failed wheel cylinder is the cause, this replaces it. Country of origin: China.
