Brake Drums

Inspection



  1. Remove loose rust and other foreign matter from the outside surfaces of the drum with a wire brush.
  2.  
  3. Check the casting itself for cracks or other obvious damage. Bluing indicates overheating. The cause should be determined.
  4.  
  5. Check the lug stud holes for ovality.
  6.  
  7. Clean the inside of the drum. Check for scoring or grooves. Any imperfections must be removed.
  8.  
  9. Check the inside diameter of the rotor. Maximum allowable inside diameter is stamped on the drum. If machining is needed to clean up the contact surface, the measurement must be taken afterwards. Replace the drum if it exceeds the specification.
  10.  
  11. Clean up the brake lining contact area with medium sandpaper. Be sure that you don't leave a directional pattern on the contact surface.
  12.  
  13. Perform a final cleaning of the contact area with a purpose-made commercial brake cleaning solvent to remove fingerprints and oily residue.
