Model ES-165 and EB-165 Interchangeability
Brake parts for the Extended Service Brake (Model ES-165) are unique
and must not be intermixed with 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 retrofi t 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.
EB ™ Roller and ES ™ Cam Interchangeability
The EB ™ Roller and the ES ™ Cam are compatible and can be used
together. Figure 5 illustrates the proper fi t of an EB ™ Roller to an
ES ™ Cam. As shown, the contact pattern is at two points and the
two parts will function satisfactorily with this fi t.
NOTE: The ES ™ Roller and EB ™ Cam are not compatible and should
not be used together.
