I have a morroso line lock that am installing and the directions suck! I am wondering if there would be any problems if I installed my brake lines in this matter. Can I run the line directly from the master cylinder to the master cylinder in on the line lock then run a line from the line lock straight to the proportioning valve that feeds the front brakes? Would this work correctly or does this even make sense? It sounds kind of stupid after reading it but I am not sure how else to explain it? I am running a CPP duel master and their proportioning valve for disc disc. Basicaly I am replacing the line that goes from the the master to the prop valve and running it through the line lock! Go ahead and fire away and please help if you can.:D Thanks, a very stupid feeling fasteddie!:eek:

I've seen it done that way but it's not the best way to do it. The problem with that was is hat when the line lock is activated it keeps pressure on only one side of the prop valve (the front brake side) but not the other (rear brake side). Placing the line lock after the prop valve means pressure on both sides of the prop valve stay the same.

Here's how mine is setup:


Also, the way you are suggesting is illegal in the NHRA rules.
General Regulations:
3:1 Brakes

...If brake system includes a differential pressure switch, line-lock installed on front brakes must have solenoid installed after the differential switch. ...

Thank you very much for the info and diaghram!:yes: Looks like I got some new lines to bend.

that electrical diagram looks a little different than the one I had saved from the past. Is the emergency brake light switch the one on the proportioning valve? Using a valve from an 80's caprice.

Could you explain the diagram's function a little?
thanks

No, that's not the one of the prop valve. I connected to the wire on the parking brake light switch. Basically when the parking brake pedal is pressed, a switch grounds the wire and lights the "BRAKE" light on the dash. What I did was to splice into it and send a second wire to the 2nd relay. It's just another way for that wire to be grounded and in turn light the "BRAKE" light on the dash. So instead of having a different light to let me know the if the line-lock is on, it lights the factory "BRAKE" light in the dash.
