line lock 67 cuda hellllllp

You can't go after the master cylinder,before the portioning valve (what your calling the distribution block) I did this and it doesn't work.It will start locking up, and you will have to bleed the front brakes off to get them to release.It throws the porporting valve into a tizzy!
You need to take either the left or right front brake line off the porpotioning block at the out side, and 'T' the left and right together.
Install the line lock before the T as it comes out of the portioning block.Then install a plug in the unused port.
I know this works, because we went through 2 line locks, before we found out the line locks were not bad. The instructions are confussing.
I also know this works, because my Valiant is set up this way, and so is my Cuda, along with my wifes Dart.
You may consider a heat shield when installing it. I know all this is a hassel, but it is the only way it will work.
I am not sure how the others got it to work the way they did it, maybe they had a T of some sort, and not a porporting valve.
Have fun.
