The MICO Lever Lock is designed to supplement a vehicle's standard parking brake by utilizing the hydraulic service brakes. Lever Locks are manually operated one-way check valves, which lock fluid under pressure in the selected brakes. Hand operation leaves the operator's feet free for clutch and throttle pedal operation. Lever Locks include one low pressure warning switch.
