While the topic of line locks is being discussed, I submit this question.
I have installed my line lock as mentioned directly in the front line, before the pressure differential switch and not only did it not work, it caused the BRAKE light to turn on. (Please forgive the terrible photo editing to add the line lock solenoid)
I then decided to read the instructions, and installed it in the line AFTER the pressure differential switch. This worked better, didn't turn on the BRAKE light, HOWEVER after about 2 seconds the truck will begin to roll just at idle. I do not know if this is a faulty line lock solenoid, a bad plunger in the solenoid, or what. But it definitely will not hold pressure to the front brakes. My hope is that its just a bad solenoid and once I replace it I will be able to hold the front tires. The solenoid is staying powered, but fluid seems to be moving through the unit.
SO the question, Can installing it as shown by HURST cause my front wheel roll problem?
