Line Lock (Brakes)

[JeepNWilly]

Anyone here have ever used a brake line lock kit on your TJ to gain 4 wheel e-brake or to replace the existing e-brake?
I destroyed my e-brake mounting points on my rear axle a while back by taking off in 4-low while the e-brake was on LOL needless to say with my 4.88 gears and in 4-low the e-brake on my rear axle came out in pieces lol.

I'm curious what the advantage is to a 4-wheel e-brake? I hadn't actually heard of this until now.

For me it is mainly to use as an e-brake.

But I can see locking all 4 wheels could come in handy on a trails where you have to sit waiting for ride to continue. Remember I drive a manual trans for those of you with automatics it is no big deal just put it in Park.

It's not an "e" (emergency) brake, technically it is a parking brake. Not sure I would trust a line lock for a daily driven vehicle. Some of the racer dudes back in the day used them on drag cars which is really what they are made for. They did cause issues from time to time. You are better off, and safer, to fix your parking brake issue.

To fix mine I would probably need the replace the back plate that bolts to the axle tube. Might be the same plate that the caliper attaches to.

I don't have any experience with them on a TJ. But my buddy does have it on his rock buggy it's pretty cool. Tow trucks use that system, great for winching. They can bleed off over a period of time though. Think that's why some call them a holding brake not a park brake.

if you break a line on the side of the system that the line lock is on, guess what happens to your hydro e-brake

Line locks are for drag racing to do the burnout. They lock up the front brakes in order to get the rears hot for a race.

That settles it no line lock then

Yeah, you broke the anchor pin off the backing plate and it will need to be replaced to fix the problem. You aren't the only one who has done it.

Lol it was a loud pop when I quickly shifted to reverse and moved to setup an anchor point for a buddy stuck on a climb in a WindRock TN. I remember after I kept hearing all kinds of grinding noise until I stopped and removed wheel and rotor. Lol haven't looked at it since it happened. Don't really use parking brake here in Florida lol

Let me preface this with saying I know brake hydraulics well enough not to trust them. All it takes is a weeping connection to bleed off the pressure and you lose you parking feature, sometimes detrimentally. Now, that said, there are a couple of solutions that are common and do work, one is commercial and is standard on a lot of big trucks with hydraulic brakes. The Mico Lock is used on service trucks when you need to lock down the vehicle a bit more securely than just the parking brake will be able to do.

Another similar but cheaper method is the Jamar lock which is manual and you just step on the brake pedal to lock the tires in place and then hit the button to close the hydraulic valve.

The problems are that you need to bring a hydraulic line into the cab so you can access the valve and the biggie is if you get excited on your way out of the rig to go help someone in trouble, you can stomp the pedal hard enough that you can't push it any further and since the lock needs equal pressure on both sides to release the valve, you may have to open a bleeder to release the brakes.

I have seen folks use a small stainless steel ball valve and a remote handle on it plumbed into a line or both lines off of the master to rig up a hydraulic parking brake. Same thing, push the pedal, close the valve and it locks the pressure in place. That method will release under any pressure differential.

mr blain is right on with his statement I used to have a tow service and had them in all of the vehicles I used the flip lever either on or off to help with the winching if the truck would slide at all I would keep tenson on the cable put in reverse spin the tires enough to dig a small hole to help in the winching not a lot of trees to tie of to in southern California so you have to be creative

I will look into fixing what I have. Probably the back plate or whatever it is called my need to be replaced.
