Push the brake shoes firmly against the drum with the hydraulic muscle of the Dorman - First Stop Drum Brake Wheel Cylinder W73609. It's a direct-fit front replacement (front left or front right) for a wide range of 1970-1973 Chrysler, Dodge and Plymouth models — including the Chrysler New Yorker, Newport and Town & Country, Dodge Challenger, Charger, Coronet and Dart, and Plymouth Barracuda, 'Cuda, Road Runner and Valiant — across all engines.

A wheel cylinder converts brake-line hydraulic pressure into the outward force that pushes the shoes against the drum. Signs the original may need replacing include brake fluid weeping at the cylinder, a soft or spongy pedal, or uneven drum braking — diagnose the cause before replacing.

  • Direct-fit replacement: engineered to match the fit, function and performance of the original wheel cylinder on the listed vehicles, then manufactured and tested for quality assurance.
  • EPDM rubber cups and boots: made with high-quality EPDM rubber for long-lasting sealing.
  • Cast iron body: 1.188 in inside-diameter bore with a 3/8-24 UNF inlet thread (3/8 thread diameter).
  • Serviceable: includes a bleeder screw; a bleeder screw cap is not included.
  • Professionally tested: the bore is surface-tested for an optimal sealing surface for the pressure cups.

Replacing the cylinder while servicing the drum brakes is a quick, cost-effective way to help maintain brake performance. Sold individually — for even, balanced braking it's best to replace the cylinders on both sides of the axle together as a matched pair. Country of origin: China.
