Dorman - First Stop Drum Brake Wheel Cylinder P/N:W13368

Keep the left-side drum brake on your classic Cadillac or Pontiac applying firm, even hydraulic pressure with the Dorman - First Stop Drum Brake Wheel Cylinder W13368. This wheel cylinder converts brake-line hydraulic pressure into the mechanical push that forces the brake shoes outward against the drum. It's engineered to drop in like the original on the listed applications, installing in the front-left or rear-left position (depending on application) on vehicles such as the 1960 Cadillac DeVille, 1960 Cadillac Series 60 Fleetwood, 1960 Cadillac Series 75 Fleetwood, 1957 Pontiac Bonneville, 1950-1957 Pontiac Catalina, 1949-1957 Pontiac Chieftain and more — see the Buyer's Guide tab for the full list.

• Cast-iron body: 1.063 in bore with surface-tested walls for an optimal sealing surface for the pressure cups.
• EPDM rubber cups and boots: high-quality seals for long-lasting performance.
• Bleeder screw included: ships with the bleeder screw; the bleeder screw cap is not included.
• 7/16-20 UNF inlet thread: matches the brake-line inlet fitting.

Replacing the wheel cylinder while you already have the drum brakes apart is a quick, sure way to help maintain brake performance. If a leaking or seized cylinder is the cause of a soft pedal or fluid seeping behind the drum, this replaces it. Signs a wheel cylinder may need replacing include fluid leakage at the wheel, a spongy pedal, or uneven shoe application. Country of origin: China.
