A line lock is a device that allows the front brakes to lock independently of the rear brakes via a switch.[1][2][3][4][5] The device is an electric solenoid that controls a valve which is placed on the front brake line, and is controlled by a switch.[1][2][3][4] Simpler systems consist of a manually operated valve which directly opens and closes the brake line, usually with a lever or tap inside the cabin of the vehicle. Normally, the valve is open and allows fluid to pass through to the front brakes.[3][4] However, when the brakes are applied and the solenoid is activated, the valve closes to trap the brake fluid, keeping the front brakes applied until the switch is released.[1][2][3][4]
