Adjusting the Drum Brakes
E
It is necessary to rotate the wheels in the direction of
forward rotation only when making adjustments.
The brake adjustment nut is located behind a slot at
the bottom of the backing plate. Tighten the nut until
you cannot rotate the wheel by hand, then back off the
adjustment 18 to 20 notches.
ROTATE THE DRUM IN THE DIRECTION OF
FORWARD ROTATION ONLY
Hydraulic Lines
F
Use care in shaping brake lines to avoid sharp bends
or kinks. Be sure and use a “Double Flaring” type of
tool on steel tubing to assure tight leakproof
connections. Be sure and use hydraulic rubber hoses
at points of flexing. Anchor hose ends to avoid stress
on tubing.
