Deliver firm, even hydraulic pressure to your drum brake shoes with the Dorman - First Stop Drum Brake Wheel Cylinder (P/N W19236). It drops in as a direct-match replacement for the front wheel cylinder on a long run of classic Studebakers built from 1954 to 1966 — including the Commander, President, Hawk, Lark, Daytona, Cruiser, Wagonaire and more — so check the "Vehicles it fits" section for the full 16-application list.
- Cast-iron body: a durable cast-iron housing sized to the original.
- EPDM rubber cups and boots: made with high-quality EPDM for long-lasting sealing.
- Surface-tested bores: each bore is surface-tested to provide an optimum sealing surface for the pressure cups.
- Bleeder screw included: ships with a bleeder screw (bleeder screw cap not included).
When the brake pedal is applied, this cylinder converts line pressure into outward piston travel that pushes the shoes against the drum. Weeping fluid at the wheel, a soft or sinking pedal, or fluid behind the drum are signs that a wheel cylinder may need replacing; if a failed cylinder is the cause, this replaces it. Inside diameter 1.063 in with a 3/8-24 inlet thread. Each listed application uses two, so order two for a complete axle. Country of origin: China.

Frequently Asked Questions
What does this wheel cylinder do?
It converts brake-line hydraulic pressure into outward piston travel that pushes the drum brake shoes against the drum. If a failed cylinder is the cause of your brake problem, this replaces it.
Which vehicles does it fit?
It's a direct-match front wheel cylinder for many Studebaker models from 1954-1966, including the Commander, President, Hawk, Lark, Daytona, Cruiser and Wagonaire. See the "Vehicles it fits" section for the full 16-application list.
How many do I need?
Each listed application uses two. This listing is for a single cylinder, so order two to replace the pair on the axle for balanced braking.
Does it include a bleeder screw?
Yes, a bleeder screw is included. A bleeder screw cap is not included.
What is it made of?
The cylinder has a cast-iron body and uses high-quality EPDM rubber cups and boots. Its inside diameter is 1.063 in with a 3/8-24 inlet thread.
