B
Brake Shoe and Adjuster Replacement
It is recommended that when brake shoes are replaced, the
adjusters and springs also be replaced. It is good practice to
do one side at a time, using the other side for reference.
Remove the three brake shoe springs and discard (1, 2,
3). Note the location of the heavy spring and the
adjuster spring (Ref. Fig. 24 on Page M-18). Hold the
shoe clamp pin (4) and compress and rotate the shoe
clamp (5) 90° to release it from the shoe clamp pin.
Remove the brake shoes, adjusters and remaining com-
ponents.
Fig. 24 Brake Shoes and Springs
Clean the backing plate with a commercial brake
cleaner. Allow to dry completely. Lubricate the friction
points of the shoes and moving anchor with Multi Pur-
pose Grease (MPG) lubricant (Ref. Fig. 22 on Page M-
17).
Be sure that the adjusting screw is screwed into the
star wheel nut until only 1 - 2 threads are exposed
Install adjuster mechanism (driver side silver, passenger
side gold). Be sure that the two teflon coated washers
are installed as shown (Ref. Fig. 22 on Page M-17). The
adjusting screw must be screwed into the star wheel nut
until only 1 - 2 threads are exposed (Ref. Fig. 25 on
Page M-18).
Fig. 25 Setting Adjuster Screw
Install the actuator piston. Be sure the hardened shim
washer is installed as shown (Ref. Fig. 22 on Page M-
17).
Always replace both brake shoes on both wheels as a
set. Install the shoes as indicated and install the shoe
clamp (5) over the shoe clamp pin (4) and rotate 90° to
lock them in place (Ref. Fig. 24 on Page M-18).
Install new brake shoe and adjuster springs. The hooked
end of the adjuster spring is inserted through the front of
the front shoe as shown (Ref. Fig. 24 on Page M-18).
The opposite end of the adjuster spring is hooked to the
adjuster with the hook end facing out. The brake shoe
springs must be installed with the light spring closest to
the adjuster mechanism with the hook installed down
through the rear brake shoe and up through the front
brake shoe. The heavy top spring is installed with both
spring hooks installed down through the brake shoes.
Check to see that the brake is functioning properly.
Install the brake drum. “Brake Drum Removal and Installa-
tion” on Page M 16
