Keep your drum brakes clamping evenly with the Dorman First Stop Drum Brake Wheel Cylinder W90549. This front-position wheel cylinder is a direct-fit replacement for the drum brakes on the 1965-1979 Volkswagen Beetle, 1965-1966 Volkswagen Karmann Ghia, 1971-1977 Volkswagen Safari and 1970-1994 Volkswagen Sedan, engineered to match the original cylinder's fit, function and performance on these applications. Mounted at the drum, it converts hydraulic brake-fluid pressure into mechanical force that pushes the brake shoes outward against the drum; replacing a leaking or seized cylinder while you service the drum brakes is a fast, cost-effective way to keep the hydraulic side working as intended.

  • Cast-iron body: the bore is surface-tested to provide an optimum sealing surface for the pressure cups.
  • Quality sealing materials: built with high-quality EPDM rubber cups and boots for long-lasting performance.
  • 0.875 in. bore: M10 x 1.0 inlet thread (10 mm thread diameter, 1.0 pitch).
  • Hardware: bleeder screw included; bleeder screw cap not included.

Sold individually. The listed applications use two per vehicle, so order 2 and replace both sides together for balanced braking. Made in China.

The cylinder has a 0.875 in. inside diameter bore and an M10 x 1.0 inlet thread (10 mm thread diameter, 1.0 pitch).

Does it include a bleeder screw?
