Adjusting The Service Brakes - Toro 30344 Operator's Manual

6. Press down on the parking brake rod and push up on
the switch until the compressed length of the switch
plunger is 0.030 inches (Figure 62, inset) . This is the
distance between the brake rod paddle and the switch
plunger housing.
7. Tighten the switch mounting screws and nuts.
8. With the parking brake disengaged, the switch circuit
should have continuity. If there is no continuity, move
the switch down slightly until there is continuity.
9. Check the adjustment as follows:
A. Engage the parking brake.
B. Press the traction pedal while the 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 that
must be corrected.
10. Install the steering tower cover and brake rod knob.

Adjusting the Service Brakes

Service Interval: After the first 10 hours
After the first 50 hours
Every 50 hours
Adjust the service brakes when there is more than 25 mm
(one inch) 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 connects to the bottom
of the brake pedals. When the cable is no longer adjustable,
the star nut on the 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 the lock arm from the right brake pedal so
that both pedals work independently of each other.
2. To reduce the free travel of the brake pedals, tighten
the brakes by loosening the front nut on the threaded
end of brake cable (Figure 63). Then tighten the rear
nut to move cable backward until the brake pedals have
13 mm to 25 mm (1/2 to 1 inch) of free travel.
1. Brake cable jam nuts
3. Tighten the front nut after the brakes are adjusted
correctly.
