Dorman - First Stop Drum Brake Wheel Cylinder P/N:W4875

Keep hydraulic pressure moving to your drum brakes with the Dorman - First Stop Drum Brake Wheel Cylinder (W4875), a front wheel cylinder that drops in as a direct-fit replacement for the 1939-1942 and 1946-1949 Studebaker Champion (All engines). Mounted in the drum, it channels brake-fluid pressure to push the brake shoes outward against the drum.

Dorman built this cylinder to match the fit, function, and performance of the original unit on the listed applications, and each one is manufactured and tested for quality assurance.

• Cast-iron body: a cast-iron housing supports the internal pistons and seals.
• EPDM rubber cups and boots: made with high-quality EPDM rubber cups and boots for long-lasting performance.
• Surface-tested bore: the wheel cylinder bore is surface-tested for an optimum sealing surface for the pressure cups.
• Bleeder screw included: ships with a bleeder screw (bleeder screw cap not included).

Specs include a 1 in inside diameter and a 3/8-24 in inlet thread. Country of origin: Taiwan. Each listed application uses two cylinders, so this one is sold individually — order two for a complete axle set and replace both sides together for balanced braking.

Signs this part may need replacing include brake fluid leaking at the drum, a soft or spongy pedal, or uneven braking; diagnose the cause before replacing.
