Frequently Asked Questions
What does a drum brake wheel cylinder do?
When you press the brake pedal, hydraulic pressure pushes the wheel cylinder's pistons outward. The pistons force the brake shoes against the drum. The W37625 is a rear-position unit.
Does the Dorman W37625 fit a 1978-1983 Chevrolet Malibu?
Yes. The 1978-1983 Chevrolet Malibu is a listed application, as are the 1982-1988 Chevrolet Camaro and 1983-1991 Chevrolet S10. Check the "Vehicles it fits" section for your exact vehicle.
What are the cups and boots made of?
The cups and boots are EPDM rubber. The cylinder bores are surface-tested to provide an optimum sealing surface for the pressure cups.
What are signs a wheel cylinder may need replacing?
Possible signs include brake fluid seeping inside the drum, fluid-soaked shoes, a soft or sinking pedal, or pulling while braking. Other brake faults cause these too, so diagnose first.
Should I replace the wheel cylinder when servicing drum brakes?
Yes. Replacing the cylinder while the drum brakes are apart is a cost-effective way to help maintain brake performance. Follow the vehicle service information for installation and bleeding.
