691 Brake Lock System
The MICO 691 Brake Lock System locks hydraulic pressure in the service brakes to supplement the vehicle's mechanical parking brake and provide extra holding in heavy-duty high frequency applications. These systems also function as an interlock to apply pressure to the service brakes when other vehicle mounted equipment is being used.
A system consists of a small electrohydraulic pump, remote mounted actuator (single and/or dual), electronic control module, and a small dash mounted user interface. The operator simply activates a switch and the 691 System automatically applies, monitors, and maintains brake-locking pressure.
Troubleshooting information on the MICO 691 Brake Lock System starts on page 16 of the Operation and Installation Instructions below. Also below are instructions for power unit or pressure switch replacement, as well as, diagnostics information.
