It just seams like it holds at half the pressure , compaired to if you just push on the pedal and try to turn the wheels . The line lock is get full 12vdc . All line connected wright in and out . Its the only thing left . Anybody run in to this ? Ken R.

On my 70 challenger its pretty similar if I don't pump the living crap out of the brakes first. Much more than the other cars(dakota and challenger09). I think you may have solved a nagging problem for me!
