Steering Home Sensor - Toro Groundsmaster 360 Service Manual

Adjusting the Parking Brake Sensor

Steering Home Sensor

Electrical System: Adjustments
When the parking brake is not set (brake latch not engaged), the parking brake
detent is positioned near the target end of the parking brake sensor so that the
sensor is closed. The parking brake detent is moved away from the sensor when
the parking brake is set (brake latch engaged) causing the sensor to open.
1. When the parking brake is not applied (brake latch not engaged), the gap
between the parking brake sensor and the tab on the parking brake detent
should be 3.8 to 4.7 mm (0.148 to 0.188 inch).
2. If the gap is incorrect, loosen the jam nuts that secure the sensor to the
brake lever. Position the sensor with jam nuts to allow correct gap between
the sensor and the brake detent tab. Tighten the jam nuts to secure the
adjustment. Torque the jam nuts to 18.4 to 22.4 N∙m (162 to 198 in-lb).
After the jam nuts are tightened, ensure that clearance between the head
of the parking brake sensor and the tab on the parking brake detent has
not changed.
3. Check that the LED on the cable end of the parking brake sensor is
illuminated when the parking brake is not applied (brake latch not engaged).
The LED should not be illuminated when the parking brake is set (brake
latch is engaged).
4. After adjustment to the parking brake sensor, use the InfoCenter display to
verify that the parking brake sensor and circuit wiring are functioning correctly;
refer to Using the InfoCenter Display for Troubleshooting (page
