Print


CAUTION
Brake shoes contain asbestos, which has been determined to be a cancer causing agent. Never clean the brake surfaces with compressed air! Avoid inhaling any dust from any brake surface! When cleaning brake surfaces, use a commercially available brake cleaning fluid.

INSPECTION



  1. Clean the drum with a rag and a little paint thinner.
  2.  


CAUTION
Do not blow the brake dust out of the drum with compressed air or lung power. Brake linings contain asbestos, a known cancer causing agent.

  1. Inspect the drum for cracks, grooves, scoring and out-of-roundness.
  2.  
  3. Light scoring may be removed with fine emery paper, Heavy scores or grooves will have to be removed by having the drum turned on a lathe. This can be done at many automotive machine shops and some service stations.
  4.  
  5. Before cutting the drum it must be measured to determine whether or not the inside dimension of the drum is within limitations after removing the score marks.
  6.  
  7. Check the drum for concentricity. An inside micrometer is necessary for an exact measurement, so unless this tool is available, the drum should be taken to a machine shop to be checked.
  8.  

Make all measurements at right angles to each other and at the open and closed edges of the drum machined surface.
