Brake Installation
1. Remove your AT brake from its shipping car-
ton and inspect it thoroughly to ensure that it
has arrived in good condition.
An accessory kit included with your brake
contains a coil wire retainer. In addition, you
may have ordered the optional brake torque
arm.
2. If used, install the Warner Electric conduit
box or conduit box/CBC-100 control combi-
nation in accordance with instructions fur-
nished with the conduit box.
3. The Warner Electric patented Autogap auto-
matically adjusts the proper operating gap
between the armature and friction face for
the life of these components.The proper gap
is approximately .050". If the armature and
friction face have moved during shipment, re-
set the Autogap by pushing the armature
against the friction material face. Release.
The armature will spring back about .050"
and the proper gap is set.
4. Slide the brake onto its shaft over its key.
If the brake is to be operated in a vertical
position, it must be mounted with the
armature fins up.
5. Install the optional Warner Electric torque arm
or the customer furnished pin. The arm must
be strong enough to withstand the brake’s
full torque capacity, and should be affixed to
the machine frame, and to the brake tangent
to its circumference in the notched attach-
ment point on the back plate. It must also be
flexible enough to compensate normal shaft
and bearing runout without causing binding
or side loading to the brake.
