Adjusting the Parking Brake Sensor
Groundsmaster 7210
16222SL Rev C
When the parking brake is not set (the brake latch not engaged), the parking
brake tab is positioned near the target end of the parking brake sensor so that
the sensor is closed. The parking brake tab is moved away from the sensor when
the parking brake is set (the brake latch engaged) causing the sensor to open.
1. When the parking brake is not set (the brake latch is not engaged), the gap
between the parking brake sensor and the tab on the parking brake should
be 2.8 to 3.8 mm (0.110 to 0.150 inches).
2. If the gap is incorrect, loosen the jam nuts that secure the sensor to the brake
lever. Position the sensor with the jam nuts to allow correct gap between the
sensor and the tab. Tighten the jam nuts to secure the adjustment. Tighten
the jam nuts to 18.4 to 22.4 N∙m (162 to 198 in-lb). After you tighten the
jam nuts, ensure that the clearance between the head of the parking brake
sensor and the tab on the parking brake is not changed.
3. Check that the LED on the cable end of the parking brake sensor is
illuminated when the parking brake is not set (the brake latch is not engaged).
The LED should not be illuminated when the parking brake is set (the brake
latch is engaged).
4. After adjusting the parking brake sensor, use the SCM to check that the
parking brake sensor and circuit wiring are functioning correctly; refer to
Parking Brake Sensor (page 5–33).
