Ive always thought it would be cool to have a line lock. My dad knows how to do it but he wont do it and he wont tell me. So im askin u guys how to properly rig one up. i mainly need to know where to put the valve and stuff. so just gimme ur input on how to rig this up
Line lock (or roll control) is an electrically controlled solenoid that goes in the front brake line. The solenoid is controlled with a (Normally off) pushbutton switch that is mounted where it can be easily accessed by the driver, like on the shifter or the steering wheel. Once installed and the brakes lines are bled, you depress the brake peddle first then the switch to activate the solenoid. Then let up on the brakes and the front brakes stay locked until you release the button. This set up is for rear wheel drive. I've never done it, but you could reverse the installation for front wheel drive.
The idea is to lock up the non-drive wheels so you can do a burnout without smokin' the brakes. Also, keeps the car from rollin' when you stage at the lights.
Looks like Pro beat me to it. You can buy the set ups at www.summit.com or Jegs, they have them for like 82 bucks or so but you can find them even cheaper for about 60 bucks so look around for good prices before you just jump ahead and buy one from summit. Good luck. Better look for a good place to hide that button from your pops, heh.
