Brake Switches
Service Brake Switch Description
The foot brake switch is on the brake link end, under the
flow plate. The switch operates when it is released by the
brake pedal lever during braking. Depressing or releasing
the switch operates a set of contacts that alternate from
open to closed to activate the Pedal Braking function of
the control. This function uses the motor to help bring the
truck to a controlled stop.
Service Brake Switch Adjustment
Adjust the switch so that it “clicks” just before the end of
pedal “freeplay” (the lag between pressing the brake and
operating the master cylinder, covered in Group 23).
Adjust switch as follows.
1. Turn key switch OFF.
2. Make sure freeplay is properly adjusted as described
in Group 23.
3. Loosen brake switch mounting screws.
4. Rotate switch against pedal until switch trips. (A
click can be heard.) Tighten mounting screws.
5. Check operation of switch by depressing brake pedal.
Switch should actuate just before the end of freeplay
(at which time you feel resistance in the pedal caused
by the master cylinder beginning to operate.)
