LINE LOCK complete kit avaliable ?

[johannes]

I'm considering installing a line lock to my rear brakes, so I can do burnouts without frying the drums.
Guess the location will be in the engine bay.

Can anyone please list up the parts I need ? preferable SUMMIT part numbers.
... as I need to get all parts shipped from US
Summit has this kit (for the new Challenger) Hurst Roll Control Kits 5671520.
...but for me to install without cutting,...I'm reasonable sure more parts are needed?

I found this tread...which rises similar questions...

Also, pictures are welcome.

Line lock does lock the front brakes so you can burnout with the rear.

I installed mine in the rear of the car, right beside where the hardline screws into the flex line to the diff, mounted it on the floor pan, got a short piece of hardline and (about a 6" piece), undid the OEM hardline and bolted it directly to the LineLock valve, then with the short additional piece of line went from the Lineock to the flex line. works great, press and hold the button, then foot on break and proceed to smoke the tires, using it this way you can roll control the car for rolling burnouts or lock it solid pending how hard you press the foot brake. works great for me.

If you put it in the front lines....

or you can put it in the rear lines.

Never occurred to me that you could put it on the back? But I "see" how you could now - it's just a matter of reversing the sequence of what you do. On the front - step on the foot brake, press the button, release the foot brake and then roast 'em. On the back - press the button, step on the foot brake and then roast 'em. Thanks for the enlightenment!

Pretty much RzeroB, difference is when it's on the front brake it's either on or off cause your holding it locked on with the button, blocking the rear allows brake control so if you want to creep forward you just ease off the brakes a little and re apply to stop forward motion, while not heating your rear drums up, just a matter of how you plumb it in. I'd have to check but maybe if you mash on the brakes and then press the button it "might" lock the rears until the button is realeased, not sure on that

[HP_Cuda]

Why would you want to lock the rears to burnout?

You would be tearing up your rear brakes?

[crash340]

you would want to lock the rears waiting for the light while building rpm on the converter or holding the clutch pedal in while holding rpm...... actually what its designed for believe it or not

I myself have only seen line-locks installed on the front brakes so it took me a couple of minutes to understand what Crash was describing. With the way Crash described the install, you are NOT applying the brakes then locking the rear brakes. What you ARE doing is closing the rear brake line BEFORE applying the brakes thus preventing brake pressure from reaching the rear brakes when you apply the brakes. Clever actually.

If you are trying to do that then just put a trans brake setup in.

You had better research the line lock that you want to buy.  I don't think you can install ALL line locks in the rear like that.  I believe SOME of them will still allow fluid to pass through while engaged....they just don't let the pressure "release".  I seem to remember reading a thread on another site that explained it. 

On some line locks you can push the button, then pump the brakes to build maximum pressure.  Fluid will flow one way but not the other.

I have an old line lock that I was thinking about installing in this way...if it blocks fluid flow in both directions when activated.

Another possible issue is that the NHRA rules dictate how the line lock can be installed.  I think they require it to be on the front.  IF you ever plan to race the car, that might be a concern to you.

You can pump through some linelocks...Thats why they label the ports, you can force the check off the seat on the "in" port, but it will positive check on the brake/out port...
 

Found that quote in a line lock post on Moparts.  That's probably the thread I remember reading.

It may be the orientation of the valve that is important. Depending on how the valve is constructed it may have a more positive seal in one direction?
