General Information
PARTS NOMENCLATURE
Bendix® ES™-165 and EB™-165 Brake
Interchangeability
Brake parts for the Bendix® ES™ (Extended Service)
brake (Model ES-165) are unique and must not be
intermixed with the Bendix® EB™ Standard Brake parts
(Model EB-165) unless otherwise instructed. These parts
consist of the camshaft, camshaft washer, return spring,
cam roller, and shoe/lining assembly. Any attempt to
operate the brake with other than its intended parts may
result in unsatisfactory performance.
“On-Road” Repair: If a vehicle should need “On-Road”
repair and ES brake hardware is not available, it is
possible to retrofit the brake with Standard Brake parts in
order to return the vehicle to service. These parts consist
of the standard shoe/lining assembly, cam roller, pin, and
return spring. The retaining springs and camshaft with
cam washer will work in this situation and do not need
to be replaced.

The EB-180-07R brake uses the ES Brake cam and
standard service lining.
