Brake Drums

Print

When servicing drum brakes, only dissemble and assemble one side at a time, leaving the remaining side intact for reference.

Inspection



  1. Clean the drum.
  2.  
  3. Inspect the drum for scoring, cracks, grooves and out-of-roundness. Replace the drum or have it "turned" at a machine or brake specialist shop, as required. Light scoring may be removed by dressing the drum with fine emery cloth.
  4.  
  5. Measure the inside diameter of the drum. A tool called an "H-gauge caliper" is used. See the Brake Specifications chart for your vehicle.

  1. Remove the lug nuts and the wheel.
  2.  
  3. One way to remove the drum is to tap the drum lightly with a mallet to free the drum if resistance is felt. Sometimes brake drums are stubborn. If the drum is difficult to remove, perform the following:
    1. Insert the end of a bent wire (a coat hanger will do nicely) through the hole in the brake drum and hold the automatic adjusting lever away from the adjuster.
    2.  
    3. Reduce the brake shoe adjustment by turning the adjuster bolt with a brake adjuster tool. The drum should now be loose enough to remove without much effort.

  5. Another way to remove the brake drum is to insert a bolt in each of the two holes in the drum.
    1. Tighten the bolts down, a popping sound should be heard, this is the drum separating from the backing plate.
    2.  
    3. Pull the drum from the backing plate.
