Description

Turn hydraulic pressure into rear braking force with the Dorman - First Stop Drum Brake Wheel Cylinder W37647. Mounted in the rear drum brake, its internal pistons are pushed outward by brake fluid pressure to force the brake shoes against the drum when you apply the brakes. It drops in as a direct replacement for the 1984-1992 Chevrolet Camaro and 1984-1992 Pontiac Firebird (all engines), engineered to match the original wheel cylinder's fit, function and performance.

Cast iron construction: cast iron body with a 0.75 in bore inside diameter.
EPDM cups and boots: made with high-quality EPDM rubber cups and boots for long-lasting sealing.
Surface-tested bore: the bore is surface-tested to provide an optimum sealing surface for the pressure cups.
Bleeder screw included: ships with a bleeder screw (a bleeder screw cap is not included) and an M10 x 1.0 (10 mm, 1.0 pitch) brake-line inlet thread.

Both listed applications use two wheel cylinders (one per rear wheel). This listing is for one; order two to service both sides together as a matched pair for balanced braking. Country of origin: China.

Frequently Asked Questions

What does this wheel cylinder do?

It's a hydraulic actuator in the rear drum brake — brake fluid pressure pushes its internal pistons outward, forcing the brake shoes against the drum to slow the wheel.

Which vehicles does it fit?

It's a direct replacement for the 1984-1992 Chevrolet Camaro and 1984-1992 Pontiac Firebird (all engines). See the Buyer's Guide tab to confirm your vehicle.

How many do I need?

Both listed applications use two wheel cylinders, one per rear wheel. This listing is for one, so order two to service both sides together for balanced braking.

Does it include a bleeder screw?

Yes, a bleeder screw is included. A bleeder screw cap is not included.

What are signs a wheel cylinder may need replacing?

Brake fluid leaking behind the drum, a soft or sinking brake pedal, or uneven rear braking. Diagnose the cause first, since other components can cause similar symptoms.
