What does a hydraulic brake line lock do?
It retains hydraulic pressure in a selected front or rear brake circuit, allowing those brakes to remain applied after the brake pedal is released.
-
How do I engage the brake line lock?
Apply the brakes to generate hydraulic pressure, then operate the valve lever to retain pressure in the selected brake circuit.
-
How do I release the brake line lock?
Return the lever to the open position to release the retained hydraulic pressure and restore normal brake operation.
-
Can the valve control the front or rear brakes?
Yes. It can be installed in either circuit depending on which wheels you want to lock.
