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.
