Keep hydraulic pressure working at the brake shoes with the Dorman drum brake wheel cylinder W45872 from the First Stop line, a front right direct replacement for the original cylinder. It fits many vehicles, among them the 1964-1967 Chevrolet Chevy II, 1964-1965 Chevrolet G10 Van and 1964 Chevrolet Chevelle. See the "Vehicles it fits" section for the full list.
A wheel cylinder turns hydraulic pressure from the master cylinder into the force that spreads the brake shoes against the drum. Dorman engineered this one to duplicate the original cylinder's fit, function and performance on the listed applications, and it is manufactured and tested for quality assurance.
- Ideal replacement: Specifically engineered as a direct match for the original drum brake wheel cylinder on the listed vehicles.
- Cost-effective fix: Dorman recommends replacing the cylinder while the drum brakes are already apart, as a quick and dependable way to help maintain brake performance.
- Quality materials: Made with high-quality EPDM rubber cups and boots.
- Professionally tested: The cylinder bores are surface-tested to provide an optimum sealing surface for the pressure cups.
A wheel cylinder may need replacing if brake fluid is seeping at the backing plate or onto the shoes, if the pedal feels soft or spongy, or if the vehicle pulls to one side while braking. Diagnose the cause before replacing parts. After installation, bleed the brake system as directed by the vehicle service information.
