(1) Raise the vehicle to free all four wheels. Install floor stands.
(2) Place transmission in NEUTRAL and be sure parking brake is released.
(3) Each brake is equipped with two eccentric cams (one for each shoe) for adjust-
ing purposes. To adjust, use an open end, or box end wrench to turn the hex
head adjusting bolts.
(4) With wrench positioned on the adjusting cam bolt in a horizontal position as
shown in Figure 17, pull downward to tighten until the shoe contacts the drum
and creates a drag when the wheel is turned.
"Back-off" the adiustment by
pushing the wrench handle upward until the wheel turns freely.
