Renew the hydraulic heart of your drum brakes with the Dorman drum brake wheel cylinder from the Dorman - First Stop line, part number W24489. It fits many vehicles, among them the 1977-1979 Ford F-700, 1977-1979 Ford F-7000 and 1980-1985 Chevrolet C60. See the "Vehicles it fits" section for the full list and engine details.
The wheel cylinder converts brake-fluid pressure into the force that pushes the shoes out against the drum. This direct replacement unit is engineered to match the original wheel cylinder's fit, function and performance on the listed applications. It is manufactured and tested for quality assurance, and it is cataloged for rear drum brake positions, upper or lower depending on the application.
- Ideal replacement: specifically engineered as a direct match for the original drum brake wheel cylinder on the listed applications.
- Cost-effective service: replacing the cylinder while the drum brakes are apart is a cost-effective step toward proper brake performance.
- Quality materials: built with high-quality EPDM rubber cups and boots.
- Professionally tested: the cylinder bores are surface-tested to give the pressure cups an optimum sealing surface.
A wheel cylinder may need replacing if you see brake fluid seeping inside the drum or onto the backing plate, notice a soft or sinking brake pedal, or feel the vehicle pull while braking. Diagnose the cause before replacing parts, and bleed the brake system after installation.

Frequently Asked Questions
What does a drum brake wheel cylinder do?
It converts hydraulic pressure from the master cylinder into mechanical force. That force pushes the brake shoes outward against the drum when the pedal is pressed.
Which trucks does the Dorman W24489 fit?
It fits many vehicles, including the 1977-1979 Ford F-700, 1977-1979 Ford F-7000 and 1980-1985 Chevrolet C60. Check the "Vehicles it fits" section to confirm your exact truck.
What are the cups and boots made of?
The W24489 uses high-quality EPDM rubber cups and boots. Its cylinder bores are surface-tested to give the pressure cups an optimum sealing surface.
What are signs a wheel cylinder may need replacing?
Signs include brake fluid leaking inside the drum or onto the backing plate, a soft or sinking pedal, or pulling while braking. Diagnose the cause before replacing parts.
Where does it install, and what should I do after installing it?
It is cataloged for rear drum brake positions, upper or lower depending on the application. Bleed the brakes afterward and follow the vehicle service information for fasteners and torque.
