Parking Brake Controls (3) Parking brake indicator. (4) Parking brake control knob. | |
The parking brake can be engaged by pulling out on the parking brake control knob (4). Parking brake control knob (4) is located on the dashboard to the right of the steering column.
A normally closed pressure switch is located on the parking brake control valve. When the parking brake engages, the pressure switch sends a signal to both the transmission electronic control module (ECM) and the Caterpillar Monitoring System. When the parking brake engages, the pressure switch activates the parking brake indicator (3) on the dashboard.
When the parking brake engages, the transmission will shift into neutral. This only occurs if the transmission is in either first speed forward or first speed reverse.
