How will I know when my 12-inch drums need replacing?

2t - 3t lazy hub 2t - 3t Brake Drum12-inch electric drums can wear very quickly on corrugated roads using standard electric magnets. The AL-KO Offroad electric Magnet will significantly reduce magnet wear.

Replace the drums if there is a visible sign of wear on the magnet or brake shoe face.

Magnet faces are generally not machined due to the height of the stud head below the surface. Machining only 2mm could raise the stud head enough to cause a collision with the magnet during rotation.


  • Remove the old studs.
  • Position the hub face down on the smaller bearing side
  • Insert drum over the hub and position to align holes
  • Insert long knurl 1/2 inch UNF studs (490302)
  • Position the stud into the hole so that the knurl is aligned correctly
  • Tap the stud into the hole to temporarily fix it into position
  • Inert hub and drum into a hydraulic press and drive studs home (min 15t of hydraulic pressure)

Ask our engineers when purchasing both the hub and drum. There is no charge for this service.

Alternatively, call us and purchase a wide range of  trailer and caravan spare parts over the phone,

Worn drums can involve replacing the drums and replacing the entire backing plate with the offroad model.
