Reseal a weeping drum brake wheel cylinder with the Dorman - First Stop Drum Brake Wheel Cylinder Kit 13620. It supplies the internal sealing components used to rebuild the wheel cylinder — the hydraulic part that pushes the brake shoes outward against the drum. It's a direct-fit repair kit for hundreds of classic applications, including the 1958-1966 American Motors Ambassador, 1960-1970 Chevrolet C10 Pickup, 1959-1966 Buick LeSabre, and 1953-1962 Chevrolet Corvette (All engines). It services front or rear drum wheel cylinders depending on the application; see the Buyer's Guide tab for the full 493-application list.

  • Includes: wheel cylinder cups (seals) and dust boots.
  • Not included: wheel cylinder pistons, expander spring, bleeder screw, bleeder screw cap, and mounting hardware.
  • Bore size: 1.125 in.
  • Built from quality components to match the original sealing parts and support reliable service life.

If fluid seepage from a worn wheel cylinder is the cause of your brake trouble, this kit reseals it rather than requiring a full cylinder. Quantity varies by application — many use two (one per side), some use one; confirm your vehicle. Country of origin: China.
