Parking Brake Switch
The parking brake switch is a normally open proximity
switch. The parking brake switch is attached to the bot-
tom of the brake pedal (Fig. 19).
Whentheparkingbrakeisnotapplied,theparkingbrake
detent is positioned near the target end of the parking
brake switch so the switch is closed. The parking brake
detent is moved away from the switch when the parking
brake is applied causing the switch to open.
Adjustment
For machines with serial numbers below 310000000
(Fig.19), the distancebetweenthe parkingbrake switch
and the tab on the parking brake detent should be from
0.048” to 0.077”(1.2 to 1.9 mm) whenthe parking brake
is not applied. If distance is incorrect, loosen lock nut
that secures switch to brake lever. Position switch to al-
low correct clearance between switch and detent tab.
Tighten lock nut to secure adjustment.
For machines with serial numbers above 310000000
(Fig.20), the distancebetweenthe parkingbrake switch
and the tab on the parking brake detent should be from
0.040” to 0.100”(1.1 to 2.5 mm) whenthe parking brake
is not applied. If distance is incorrect, loosen jam nuts
that secure brake switch to brake pedal. Position switch
with jam nuts to allowcorrect clearance between switch
and brake detent tab. Jam nuts should be torqued from
162 to 198 in--lb (18.4 to 22.4 N--m). After jam nuts are
tightened, make sure that clearance has not changed.
After adjustment to the parking brake switch, use the
Diagnostic Display (see Special Tools in this chapter) to
verifythat brakeswitch andcircuitwiring arefunctioning
correctly (see Parking Brake Switch in the Component
Testing s ection of this chapter).
