Proper Line-lock use?
Well of course Line=locks are used to lock the front for a burn-out but I've been thinkin on installing the lock to the rear & using it to lock the pressure from going to rear brakes thus allowing you to moderate the front brake to allow you to roll a little when required to keep things nice & straight!!
Any thoughts on this ? Or am I a little out of the norm in thinkin

That does not sound good at all. If you want to modulate between the front and rear get a brake regulater valve. This is what it is designed for. I have seen line loks on the rear but only for front drive cars. They are not designed to modulate pressure.

Linelock is also useful if you are stopped at a stop sign or red light on an uphill slope and some moron pulls up behind you 2" from your rear bumper!
Lets you pull away without drifting backwards!

Line locks are one direction only. You can put the line lock on and then hit the brakes. The pressure passes right through the linelock. Returning is the only place the linelock works. So if you put the linelock on the rear brakes and then hit the pedal the pressure would pass through the linelock effectively locking up the rear brakes anyway.
This is a safety feature. On the front even with the linelock turned on the brakes would still work.

What I was thinkin was to install one so the rear would recieve no pressure, so you could moderate your front to let yourself roll a little while your doing the burn-out.
"Line locks are one direction only." So I guess you couldn't install one backwards on the rear to acomplish this.
Thanks anyway on the linelock norvalwihelm

Actually you can install a line-lock on the rear system...mount it backwards.
A friend did this on his car. It stops the pressure from reaching the rear brakes and allows him to hold his foot on the brake pedal while doing the burnout...then he lets his foot off the pedal when he wants to pull forward. Works for him...I installed mine the "correct way" on the front brakes.
Good luck,
Jeff

Seems to me that you need a proprtioning valve mounted in the cabin like race cars use. Dial down the rear pressure and your can do what you want then return the bias to normal for driving.

If your going through the trouble of mounting it on the rear why not just mount it on the front and do it the right way. I don't know why you would want to mount it this way. If you are driving a stick car it would require some fancy foot work.

Yep on a stick car it would require some fancy footwork.
But in a non-race car don't you think the ability to allow your car to roll a little when you want would be usefull in keeping it straight?

You can't see any use in having the ability to block brake pressure to the rear, so your foot only controls the front brakes
Ya I guess not
no point in NOT having the rear brake pads squeezin the rotors when spinnin the tires

I use a line lock as a parking brake. I eliminated my parking brake shoes and cables and use the rear calipers as a parking brake instead. All I have to do is to shut off the car and pump the brakes to lock. I used a relay to activate the locking device. It will automatically release the brakes every time you start the car. So far, it works very well. I also have an inline switch so that I can keep the lock on at all times if I want. That way, the car is harder to steal. A regular thief would not know how to figure on releasing the brake lock.

Interesting, my Hurst Roll Control Line Lock advises AGAINST leaving it active for more than something like 30 seconds at a time.
