Inspect suspension for wear.
Check tightness of hanger bolt, shackle bolt, and U-bolt nuts per recommended torque values.
Check brake linings, brake drums, and armature faces for excessive wear or scoring.
Check brake magnets with an ohmmeter. The magnets should check 3.2 ohms. If shorted or worn excessively, replace.
Lubricate all brake moving parts, using a high temperature brake lubricant. (Lubriplate or equivalent). Caution: Do not get grease or oil on brake linings or on magnet face.
Remove any rust from braking surface and armature surface of drums with fine emery paper or crocus cloth. Protect bearings from contamination while so doing.
