The steel separator plates (14) must be flat, and not scored or
discolored. They should measure 1.5 mm ±0.12 mm (0.060
±0.005 inches). The three notches (on the outside of the
separator plates) that engage the pins should not show any
deformation. Inspect the housing, and if necessary ream the
holes to 7.976 ±0.025 mm (0.314 ±0.001 inches). If reaming
does not clean up the holes, replace the housing. Replace any
plates or pins that show signs of wear or damage.
5.
The free length of springs should measure at least 25.7 mm
(1.010 inches). Replace any springs that have collapsed or are
bent. Before installing new springs, compress them completely
several times. This will preset the springs to the proper initial
installation height.
6.
Closely examine the diaphragm (10) for holes or tears. If there
are any holes or tears, replace the diaphragm. Make sure the
radius on the diaphragm plate is smooth and polished, and
check the diaphragm cover to make sure there are no sharp
edges that might damage the diaphragm.
NOTICE
Before reassembling the brake,
make sure that all gasket surfaces
as well as the diaphragm and
corresponding surfaces of the housing and cover are
clean and dry.
Disc Brake Assembly and Installation

Holding the outer race on its side, insert the one-way clutch
with its wear plates (11) partially into the outer race (17).

before slipping the inner race (16) inside the one-way clutch.
Slide the one way clutch all the way into the outer race.
WARNING
Check the direction of rotation of
the one-way clutch by holding
onto the outer race with the small
end of the inner race toward you. The inner race MUST
turn clockwise, and immediately lock when turned
counterclockwise.
NOTICE
It may be necessary to slightly
rotate the one-way clutch to fully
insert it into the outer race.
