Dorman - First Stop Drum Brake Wheel Cylinder P/N:W37799

$11.99

Description

Keep your rear drum brakes answering every press of the pedal with the Dorman - First Stop Drum Brake Wheel Cylinder (P/N W37799). This rear wheel cylinder converts hydraulic pressure from the brake system into the outward piston force that pushes the brake shoes against the drum, and it installs as a direct-fit replacement for the 1991-1993 Isuzu Stylus and 1988-1993 Pontiac LeMans.

Rear drum application: cataloged as the rear drum brake wheel cylinder for the listed vehicles.
Mechanical job: its internal pistons move outward under hydraulic pressure to apply the brake shoes, then retract as pressure releases.
Signs it may need replacing: brake fluid weeping at the backing plate, a soft or slowly sinking pedal, or reduced braking at the rear — inspect for these before ordering.

If a leaking or seized wheel cylinder is the cause of your symptoms, this unit replaces it. For even, balanced braking it is good practice to service the opposite side at the same time and to inspect the shoes, springs, and hardware during the job. Bleed the brake system after installation and confirm fitment for your vehicle.

Buyer's Q&A

Frequently Asked Questions

What does this wheel cylinder do?

It converts hydraulic pressure into outward piston force that pushes the rear drum brake shoes against the drum, then lets them retract when you release the pedal.

Is this a front or rear wheel cylinder?

It is cataloged as the rear drum brake wheel cylinder for the listed applications.

Which vehicles does it fit?

It is a direct-fit replacement for the 1991-1993 Isuzu Stylus and 1988-1993 Pontiac LeMans. Check the "Vehicles it fits" section to confirm the fit for your vehicle.

What are the signs my wheel cylinder may need replacing?

Watch for brake fluid weeping at the backing plate, a soft or slowly sinking pedal, or weaker rear braking. Diagnose the cause before replacing, since these signs can have other sources.

Should I replace anything else at the same time?

For even, balanced braking it is good practice to service the opposite side together and to inspect the shoes, springs, and hardware. Bleed the brake system after installation.
