Trailer Drums for Trailer Brake Axles
Trailer brake hub drums 12"x2" rated at 3000 Lbs each for 5200 Lb trailer axles with 6 lug bolts on a 5-1/2" bolt pattern. When the brake drum exceeds the maximum diameter cast on the drum, it should be replaced. Brake drums that have been re-machined must be thoroughly checked for chips before re-installation. The drum surface in contact with the magnet is called an armature surface. If the armature surface is unevenly worn or badly scored, the brake drum should be replaced.
