Brake Adjustment
Adjust the service brakes when there is more that one
inch of “free travel” of the brake pedals. Free travel is
the distance the brake pedal moves before braking
resistance is felt.
Adjust where brake cables connect to brake pedal
mount. When cable is no longer adjustable, star nut on
inside of the brake drum must be adjusted to move
brake shoes outward. Brake cables must be adjusted
again after star nut is adjusted.
1. Disengage lock arm from left brake pedal so both
pedals work independently of each other.
2. To reduce free travel of brake pedals:
A. Loosen front nut on threaded end of brake cable
(Fig. 12).
B. Tighten rear nut to move cable toward the rear
until brake pedals have 1/2 to 1 in. of free travel.
C. Tighten front nut after adjusting.
3. When brake cables cannot be adjusted to get free
travel within 1/2 to 1 in., star nut inside brake drum must
be adjusted. Before adjusting the star nut, loosen brake
cable nuts to prevent unnecessary strain on the cables.
4. Loosen (do not remove) the five (5) wheel lug nuts.
5. Jack up machine until front wheel is off the floor. Use
jack stands or block machine to prevent it from falling
accidentally.
6. Remove wheel nuts and slide wheel off the studs.
Rotate the brake drum until adjusting slot is at the top
and centered over star-nut (Fig. 13).
7. Use a brake adjusting tool or a screwdriver to rotate
star nut until brake drum locks because of outward
pressure of brake shoes (Fig. 14).
8. Loosen star nut approximately 12 to 15 notches or
until brake drum rotates freely.
9. Install wheel onto studs with five (5) wheel nuts.
Tighten the wheel lug nuts.
10. Remove jack stands or blocking and lower machine
to floor. Tighten wheel lug nuts to a torque of 45 to
55 ft-lb.
11. Adjust brake cables (see step 2 of this procedure).
