Brake Drums


Removal & Installation

Dust and dirt accumulating on brake parts during normal use may contain asbestos fibers from production or aftermarket brake linings. Breathing excessive concentrations of asbestos fibers can cause serious bodily harm. Exercise care when servicing brake parts. Do not sand or grind brake lining unless equipment used is designed to contain the dust residue. Do not clean brake parts with compressed air or by dry brushing. Cleaning should be done by dampening the brake components with a fine mist of water, then wiping the brake components clean with a dampened cloth. Dispose of cloth and all residue containing asbestos fibers in an impermeable container with the appropriate label. Follow practices prescribed by the Occupational Safety and Health Administration (OSHA) and the Environmental Protection Agency (EPA) for the handling, processing, and disposing of dust or debris that may contain asbestos fibers.

  1. Before servicing the vehicle, refer to the Precautions Section.
  3. Remove the tire and wheel assembly.
    Use of a brake drum puller or a torch is not recommended. Brake drum distortion can result.

    If the brake drum is rusted to the axle shaft pilot diameter, tap the center of the brake drum between the wheel studs.

  5. Remove the brake drum.
  7. If equipped, remove the brake drum retaining clips.
  9. If the brake drums will not come off, follow these steps.
  11. Move the brake shoe adjusting lever off the brake adjuster screw.
  13. Loosen the brake shoe adjuster screw nut by adjusting the nut upward.
  15. Using the special tool, 134-R0191, measure the brake drum inside diameter.
  17. Install a new brake drum if the maximum inside diameter exceeds the specification shown on the outside of the brake drum.

To install:

Whenever a wheel is installed, always remove any corrosion, dirt or foreign material present on the mounting surfaces of the wheel or the surface of the wheel hub, brake drum or brake disc that contacts the wheel. Installing wheels without correct metal-to-metal contact at the wheel mounting surfaces can cause the wheel nuts to loosen and the wheel to come off while the vehicle is in motion, causing loss of control. Failure to follow these instructions may result in personal injury.

  1. Clean the wheel hub mounting surface and wheel pilot.
  3. Install the tire and wheel assembly.
