Give your drum brakes a fresh hydraulic actuator with the Dorman drum brake wheel cylinder W370042 from Dorman - First Stop. It converts brake-fluid pressure into the force that pushes the brake shoes out against the drum. It fits many vehicles, among them the 1995-1998 Ford F-250, 1999-2000 Ford E-350 Super Duty and 2003-2004 Ford E-350 Club Wagon, and it is cataloged for the rear left position. See the Buyer's Guide tab for the full list of applications and engine details.

  • Direct replacement: Engineered as a direct match for the original drum brake wheel cylinder on the listed applications.
  • Cost-effective service: Dorman notes that replacing the cylinder while the drum brakes are apart is a fast, cost-effective way to help maintain brake performance.
  • Quality materials: Built with high-quality EPDM rubber cups and boots.
  • Professionally tested: The cylinder bores are surface-tested for an optimum sealing surface for the pressure cups, and each unit is manufactured and tested for quality assurance.

A wheel cylinder may need replacing if you see any of these signs:

  • brake fluid seeping at the drum
  • fluid-soaked brake shoes
  • a soft or low brake pedal
  • the vehicle pulling to one side under braking

Diagnose the cause first. If the wheel cylinder is the source, this unit replaces it. Inspect the shoes, drum and hardware during the same job, and bleed the brake system as directed by the vehicle service information.

Frequently Asked Questions

What does a drum brake wheel cylinder do?

It converts hydraulic pressure from the brake system into mechanical force. That force pushes the brake shoes outward against the drum when the brake pedal is pressed.

Yes. The 1995-1998 Ford F-250 is a listed application, cataloged for the rear left position. It also fits models such as the 1999-2000 Ford E-350 Super Duty; see the Buyer's Guide tab for your vehicle.

What are the cups and boots made of?

The cups and boots are high-quality 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?

Common signs include brake fluid seeping at the drum, fluid-soaked shoes, a soft or low pedal, or pulling to one side when braking. Diagnose the cause before replacing parts.

Should I replace the wheel cylinder during a drum brake job?

Dorman notes that replacing it while servicing the drum brakes is a fast, cost-effective way to help maintain brake performance. Bleed the brakes afterward per the service information.
