Line Lock - front or rear??

-
If you have to ask that question.... maybe you should not have a line lock. Lol!:rofl:
 
:BangHead::BangHead::BangHead::BangHead::wtf:
Assuming it's rear wheel drive you realize that you want to lock up the front wheels so you can heat up the rear tires....correct?
 
You can put them on the back. You engage the line lock and shut the fluid off from going to the rear. You then hold the car by putting on the brake which only activates the front.

If you have a stick you would need 3 feet! LOL
 
I had one plumbed into the rear for some time up until recently having had an issue with it and moved it to the front (which I like better) With it on the rear you have two additional operations to do whilst doing a burnout along with controlling the throttle, shifting, and holding the steering wheel: hold down or flip the switch to engage the line lock, and hold the brake with your other foot. If you can walk and chew gum at the same time or maybe rub your belly and the top of your head in circular motions with both hands while tap dancing you might could handle the line lock on the rear but having it on the front is slightly less “busy”

Front. Why would you put it on the rear? Have you got a honda?

You boneheads realize if you flip the line lock around, you can block brake pressure from the rear brakes, essentially accomplishing the same thing as plumbing the linelock in the front brake line, right? The only difference is your foot acts as the "switch" if plumbed in the rears, vs if plumbed in the front.

I've done it both ways and am curious what others prefer.
 
I actually used a mico trailer brake as my linelock for years. I had it hooked to the front wheels, and I really liked how it worked. I would set the brake, hit the momentary switch, and the trailer brake would hold, until I kicked the brake pedal to release it. I didn't have to hold the contact switch, so I could make the shift from second to third in the water. The solenoid finally quit, so I checked into a replacement. $550!?! Just ordered a summit linelock for $53 today.

lol, guilty as charged!
 
Actually, I have been debating on putting a line lock on both front and rear, running it through a 2 step for a "poor mans trans brake". I have all the parts to do it, just haven't messed with it yet.
 
Just hook the damn thing up the way it was designed. To the front wheels. Ever see a guy stage with the line lock and leave the line skidding the front wheels? :BangHead::BangHead::BangHead::rofl:
 
Sorry for being a “bone head” sir but why would you stop rear brakes from working? It’s a safety thing.

Its for heating the rear tires at the race track...makes it easier to do a burnout. Click it on to hold the front brake pressure and let the rears go.
 
At some tracks, in some categories it is illegal, but I don't recall seeing anything from NHRA about it....usually it is a class specific thing.
 
Yes, the line lock is for doing burnouts and shouldn't be used for anything else. It's hooked to the front brake lines only to keep the car from moving forward while doing a burn out. Nothing more.
 
Line locks can most certainly be installed to block pressure from the rear brakes, in the rear brake line, making burnouts easier to control (in some folks' opinion) by using your foot to control front brake pressure as opposed to having them controlled by an on/off switch. I've done it both ways on a couple cars and either way works fine.

I just checked the 2020 NHRA rules, and it appears that NHRA prohibits plumbing line-locks in rear brake lines in some pro classes, but is not specified in the general requirements. All it says is that "All line-locs (electric or hydraulic) must be self-returning to normal brake operating mode" - meaning momentary switch is required, I'm assuming. I've noticed quite a few guys at the track run them on the rear lines.

I must ask because it doesn't make any sense to me, Why would you want or need to control the rear brakes during a burnout? Don't you control wheel speed with the long pedal on the right?

I think you may be misunderstanding. When you put the line lock in the rear line, you turn it around, so when the solenoid is activated, it simply blocks pressure from the rear brakes. It acts the same as plumbing the solenoid in the front. The only difference is it's your foot controlling when and how much the front brakes are applied vs your thumb on a switch during a burnout. And yes, your right foot still controls wheel speed.
 
Well that's a mighty strange way to do a burnout. It ads a extra step and a extra pedal compared to the conventional way. Whatever trips your trigger.
