Dorman - First Stop Drum Brake Wheel Cylinder P/N:W18009

Keep your rear drum brakes pushing firm and even with the Dorman - First Stop Drum Brake Wheel Cylinder W18009. It drops in as a direct-fit replacement for the 1960-1963 Chevrolet K20 Pickup, 1960-1963 Chevrolet P20 Series, and 1960-1963 GMC 2500 Series (All engines). Dorman engineered this cylinder to match the original's fit, function, and performance on the listed applications, and each unit is manufactured and tested for quality assurance.

Mounted in the rear drum brake, the wheel cylinder uses hydraulic pressure from the master cylinder to push the brake shoes outward against the drum. Replacing it while servicing your drum brakes is a fast, cost-effective way to help keep the hydraulic side working as intended.
