Brake Drums

CAUTION:

Manual adjustment of the rear brake drum assemblies should only be done when the rear brake shoes are replaced, new drums are installed or existing drums are machined. If the rear brake drum assembly is not adjusted correctly, brake drag, grab, lock, overheating and fade may occur. See BRAKE SHOE ADJUSTMENT , .

Remove the brake drum. See BRAKE DRUM , .
Inspect the brake drum and measure the brake drum inside diameter in a minimum of 4 places around the circumference of the brake drum. Record the measurements.

Install new brake drum if any diameter measurement is greater than the maximum specification. See BRAKE SPECIFICATIONS .
Install new brake drum if cracked. See BRAKE DRUM , .
Heavily scored brake drums, similar to that caused by shoes worn down to the backing plate, should be machined. In order to machine, drums must be below the maximum diameter specification. See BRAKE SPECIFICATIONS .
