Description

Keep your rear drum brakes applying even, hydraulic pressure with the Dorman - First Stop Drum Brake Wheel Cylinder W93337. Mounted in the rear drum brake, it converts hydraulic line pressure into the outward push that presses the brake shoes against the drum. It drops in as a direct-fit rear replacement for the 1966-1973 Volkswagen Fastback, 1966-1973 Volkswagen Squareback, 1971-1972 Volkswagen 411, and 1973-1974 Volkswagen 412 [All] — these applications use two cylinders per vehicle.

Direct-fit design: engineered to match the fit, function and performance of the original wheel cylinder on the listed vehicles, and manufactured and tested for quality assurance.
EPDM rubber cups and boots: made with high-quality EPDM rubber for long-lasting performance.
Surface-tested bore: the wheel cylinder bore is surface-tested to provide an optimum sealing surface for the pressure cups.
Cast-iron body: features a 0.875 in inside-diameter bore and an M10 x 1.0 brake-line inlet thread; a bleeder screw is included (bleeder screw cap not included).

Swapping the wheel cylinder while you already have the drum brakes apart is a practical, cost-effective time to do the job. Country of origin: Italy.

Frequently Asked Questions

Which vehicles does the W93337 wheel cylinder fit?

It's a rear direct-fit for the 1966-1973 VW Fastback and Squareback, 1971-1972 VW 411, and 1973-1974 VW 412. Each of these uses two cylinders—see the Buyer's Guide tab for the full list.

What does a drum brake wheel cylinder do?

It converts hydraulic pressure from the brake line into outward force that pushes the drum brake shoes against the drum. Fluid leaks or a soft pedal can be signs it may need replacing.

Does it come with a bleeder screw?

Yes—the cylinder includes a bleeder screw. A bleeder screw cap is not included.

What are the bore and inlet specs?

It has a 0.875 in inside diameter (bore) and an M10 x 1.0 brake-line inlet thread. The body is cast iron.

Should I replace both rear wheel cylinders?

Replacing both sides as a matched pair is recommended for balanced braking. These applications use two cylinders, so order the quantity you need for the job.
