Dorman - First Stop Drum Brake Wheel Cylinder P/N:W134494
Get your drum brakes back to proper hydraulic operation with the Dorman - First Stop Drum Brake Wheel Cylinder W37263, a Dorman drum brake wheel cylinder designed as a direct replacement for the original unit. It fits many vehicles, among them the 1993-1994 Ford F-250, 1993-1994 Ford E-250 Econoline and 1990-1994 Ford E-350 Econoline. See the Buyer's Guide tab for the full list of applications.
When you press the brake pedal, the wheel cylinder turns hydraulic pressure into piston movement that pushes the brake shoes out against the drum. This unit is listed for both the rear left and rear right positions. Dorman notes that replacing the wheel cylinder during drum brake service is a fast, cost-effective way to help maintain brake performance.
Replacing both rear wheel cylinders together is recommended for even, balanced braking.
