To use a line locker, step on the brakes and push the line lock button. When you release the brake pedal, you’ll leave your front brakes on but disengaging your back brakes, leaving those wheels free to spin, burn and make smoke. Release the line lock button to release the front brakes and move forward. Like burnouts, this device is almost always illegal and is quite dangerous.
