Brake Drums


Removal & Installation

Full Floating Axles

To remove the drums from full floating rear axles, the axle shaft will have to be removed. Full-floating rear axles can be identified by a bearing housing that protrudes through the center of the wheel.

  1. Remove or disconnect the following:

    Axle shaft
    Retaining ring, key and adjusting nut
    Hub and drum


To install:

  1. Install or connect the following:

    Hub and drum to the tube
    Adjusting nut
    Key and retaining ring
    Axle shaft and wheel


Semi-Floating Axles
  1. Raise and support the vehicle safely.
  3. Mark the relationship of the wheel to the hub and remove the wheel.
  5. Mark the relationship of the drum to the hub and pull the drum from the brake assembly. If the brake drums have been scored from worn linings, the brake adjuster must be backed off so the brake shoes will retract from the drum. The adjuster can be backed off by inserting a brake adjusting tool through the access hole provided. In some cases the access hole is provided in the brake drum. A metal cover plate is over the hole. This may be removed by using a hammer and chisel.
