Adjusting The Service Brakes - Toro 30343 Operator's Manual

6. Press down on parking brake rod and push up on
switch until compressed length of switch plunger
is .030 inches (Figure 50, inset). This the distance
between the brake rod paddle and switch plunger
housing.
7. Tighten switch mounting screws and nuts.
8. With parking brake disengaged, the switch circuit
should have continuity. If there is no continuity,
move switch down slightly until there is continuity.
9. Check adjustment as follows:
Engage the parking brake. Depress the traction
pedal while engine is running and the PTO lever
is disengaged. The engine should stop within 2
seconds. If engine stops, the switch is operating
correctly; thus, continue operation. If engine does
not stop, there is a malfunction in the interlock
system.
10. Install steering tower cover and brake rod knob.

Adjusting the Service Brakes

Service Interval: After the first 10 hours
After the first 50 hours
Adjust the service brakes when there is more than one
inch (25 mm) of "free travel" of the brake pedals, or
when the brakes do not work effectively. Free travel
is the distance the brake pedal moves before braking
resistance is felt.
The brakes should be checked for adjustment after
the first 10 hours of operation and should only need
adjusting after considerable use thereafter. These
periodic adjustments can be performed where the brake
cable connect to the bottom of the brake pedals. When
the cable is no longer adjustable, the star nut on inside
of the brake drum must be adjusted to move the brake
shoes outward. However, the brake cables must be
adjusted again to compensate for this adjustment.
1. Disengage lock arm from right brake pedal so both
pedals work independently of each other.
2. To reduce free travel of brake pedals — tighten the
brakes — loosen front nut on threaded end of brake
cable (Figure 51). Then tighten rear nut to move
cable backward until brake pedals have 1/2 to 1 inch
(13 mm to 25 mm) of free travel. Tighten front nut
after brakes are adjusted correctly.
