Before removing a horse trailer from jack stands:
- Remove all wheels and hubs or brake drums. (Note which spindle and brake the drum was removed from so it can be reinstalled in the same locations.)
- 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.
- Inspect oil or grease seals for wear or nicks. Replace if necessary.
