Dorman - First Stop Drum Brake Wheel Cylinder P/N:W37419

$19.99

Description

Help your rear drum brakes apply the shoes evenly with the Dorman drum brake wheel cylinder W37419 from the First Stop line, which uses hydraulic pressure from the brake system to drive its pistons and press the brake shoes against the drum. It fits many vehicles, among them the 1990-1993 Subaru Loyale, 1985-1991 Subaru XT and 1974-1989 Subaru DL. See the Buyer's Guide tab for the full list and engine details.

Dorman engineered this direct-replacement cylinder to match the original wheel cylinder's fit, function and performance on the listed applications. Each unit is manufactured and tested for quality assurance.

Direct match: Designed to directly match the original drum brake wheel cylinder on the listed vehicles.
EPDM rubber cups and boots: The pressure cups and boots are made with high-quality EPDM rubber.
Surface-tested bores: The cylinder bores are surface-tested to give the pressure cups an optimum sealing surface.
Cost-effective service: Dorman calls replacing the wheel cylinder during a drum brake service a quick, cost-effective step for maintaining brake performance.

A wheel cylinder may need replacing if you see brake fluid seeping at the backing plate or inside the drum, fluid-soaked shoes, a soft or low brake pedal, or a pull to one side when braking. Other brake components can cause the same symptoms, so diagnose the cause before replacing parts. Replacing the wheel cylinders on both sides together is recommended for balanced braking.

Frequently Asked Questions

What does a drum brake wheel cylinder do?

It uses hydraulic pressure from the brake system to push its pistons outward, which forces the brake shoes against the drum. This one is cataloged for the rear drum brakes.

Which vehicles does the Dorman W37419 fit?

It fits many Subaru models, including the 1990-1993 Subaru Loyale, 1985-1991 Subaru XT and 1974-1989 Subaru DL. Check the Buyer's Guide tab to confirm your exact vehicle.

What are the cups and boots made of?

The pressure cups and boots are made with high-quality EPDM rubber. The cylinder bores are surface-tested to give the cups an optimum sealing surface.

What are signs a wheel cylinder may need replacing?

Signs include brake fluid leaking at the drum or backing plate, fluid-soaked shoes, a soft pedal, or pulling while braking. Other parts can cause similar symptoms, so diagnose the cause first.

Should I replace both wheel cylinders at the same time?

Replacing both sides together is recommended for balanced braking. Dorman also notes that changing the cylinder while the drum brakes are being serviced is a cost-effective step.
