Line Locks Revisited

[Chris DeGidio]

We've always installed it to lock the front brakes.

One other thing to think about on this. If you block the line going to the rear brakes with a line lock solonoid the piston in the master cylinder is not going to want to move since the fluid in the line would build pressure very fast with little pedal movement, therefore making it very hard to build pressure in the front brakes. Also if you can build pressure you would have to hold your foot on the brake pedal during the burnout to maintain it. If you want to do a rolling burnout why not just set the brake pressure lower with the line lock on the front (ie if you usually set it at 800 just use 400 or whatever works for you) so the car will still roll a little bit when it comes out of the water box.

Thanks for the comments. I have always seen it done the "normal"
way of locking the front brakes.

But Bob Mazzolini recommends using it to lock out the rears so
you can do your burn out and just use the brake pedal to control
speed with the front brakes. This is how he has his SS/AH car
set up.

I could be wrong on this, but wasn't the line loc originally designed to hold stick shift cars from rolling on the starting line by holding pressure to the front brakes.

Phil stick to using them on the front, who knows what kind of exotic brake setup that AH car could have on it.

[Philip Saran]

George that is exactly what I'm going to do.

But I have seen Mazzolini's Hemi Cuda up on the lift and the line lock is plumbed
in the brake line running to the rear. I guess he uses it so the rears are unlocked
and you just do a burn out and then stop with the front brakes.

Mine will be plumbed for the fronts only.
