hand brake pull rod to its proper length— 15N" between
centers. This can be accurately measured from the back of the front
hole to the back of the slot. Assemble pull rod to the hand brake
and cross shaft levers.
3. Hook up pull back spring and set the brake pedal stop so that
the brake pedal clears the floor board %".

rod to its proper length. Connect up pull rod.
5. To obtain proper clearance between brake cable and front wheel—loosen
clamp screw that holds the rear end of cable in the frame bracket,

as far as it will go, rotate the cable up and inward by grasping
the sleeve with a pair of pliers until the cable clears the tire
and frame N" to %". Hold the cable and firmly tighten
the clamp screw. Turn wheels to the right and left to set cable
and re-check for proper clearance.

the front and rear brake rods to their proper lengths. NOTE: The
front

them. This is done by pulling back on the rod end of the cable
so that the pull does not move the cam lever "A" and
screwing rod into the cable end. Connect up pull rods.

Centralize brakes on each wheel by loosening centralizer bolt "C," and
tapping it up and down to make sure that the centralizer is free.

rotating wheel forward, until the high spot on the brake drum is
reached, hold in this position and tighten the brake adjusting
screw "E" firmly, then tighten centralizer bolt "C."
9. Loosen up on the brake adjusting screw until the shoes just
clear drums. Tighten the check nuts "D..'
10. Depress brake pedal and check for equalization, loosening up
on the tight brakes until all are equal. Make sure not to have
over 50% of brakes on front. Side to side equalization of brakes
is important.
Road test car, apply brakes to check action of brakes at light,
medium and maximum pedal pressures.
