Keep the rear drum brakes on your classic BMW 2002 working the way they should with the Dorman - First Stop Drum Brake Wheel Cylinder W37425. Mounted at the rear axle, this wheel cylinder converts hydraulic pressure from the brake system into the outward force that pushes the brake shoes against the drum. Dorman engineers it to match the fit, function and performance of the original on the listed applications, so it drops in as a direct-fit replacement for the 1969-1976 BMW 2002, 1969-1971 BMW 2002TI, and 1971-1974 BMW 2002TII (All engines).

  • Cast-iron body: with a 0.625 in bore for the pressure cups.
  • EPDM rubber cups and boots: for long-lasting sealing performance.
  • Bleeder screw included: the bleeder screw cap is not included.
  • Surface-tested bore: checked to provide an optimum sealing surface, with an M10 x 1.0 inlet thread.

Replacing the wheel cylinder while servicing the drum brakes is a cost-effective way to help maintain reliable brake operation. Signs a wheel cylinder may need replacing include brake fluid seeping behind the drum, a soft or sinking pedal, or uneven rear braking. Made in Italy. Sold individually; these applications use two per vehicle, so order 2 for a complete rear-axle replacement, and replace both sides together for balanced braking.
