Keep your vintage Dodge truck stopping safely with the Dorman First Stop Drum Brake Wheel Cylinder W17786. It drops in as a direct-fit replacement across a range of 1948–1956 Dodge trucks — the B-1, B-2, B-3, B-4, C-1, C-3 and C-4 (All engines) — and, per the catalog, serves both front and rear drum-brake positions. Mechanically, the wheel cylinder converts hydraulic line pressure into the outward force that pushes the brake shoes against the drum; if a leaking, seized, or worn wheel cylinder is behind soft pedal or a pull, this replaces it.
- Cast iron body: a rigid housing built to withstand hydraulic pressure.
- EPDM rubber cups and boots: the sealing and dust-boot elastomers for long-lasting performance.
- Surface-tested bores: the cylinder bores are surface-tested to provide an optimum sealing surface for the pressure cups.
- Specs: 1.5 in inside diameter with a 3/8-24 in inlet thread; bleeder screw included, bleeder screw cap not included.
Engineered to match the original wheel cylinder's fit, function and performance on the listed applications; manufactured and tested for quality assurance. Made in China.
