Brake Drums
Electric Brake Drums
Brake drums are selected or nominated by the drum diameter, the wheel drilling pattern and in the case of hub drums, the machining profile and appropriate bearings. AL-KO can provide brake drums drilled to suit the majority of popular wheel drilling patterns ex stock and can manufacture to suit other drilling patterns on request. The table below lists popular electric brake drums.

Brake drums are available in many formats, including undrilled, drilled, studded (with studs & nuts) and with full bearing kits. It is important to select the appropriate brake capacity and to seek advice from AL-KO on the appropriate axle machining profile and bearing configuration to carry and stop the required load given the wheel size that is to be fitted.
The inside drum face where the studs are fitted on the electric hub drums is a machined surface on which the electromagnet runs. When replacing magnets it is recommended that the inside drum face be re-machined or the magnet performance will be affected.
Do not machine the magnet face to be any closer than 0.3mm from the head of the wheel studs.
On a new magnet the face is machined flat.
