ABS delete and Line lock

[LETZRIDE]

Im looking at deleteing the ABS since it doesnt work anyways...rather then buying one of those kits for 150$ or so, I was thinking of making my own...it looks like they consist of just a proportioning valve, some fittings, pre fabbed lines, and instructions.

Well I have extra brake line, and fittings are cheap. Proportioning valves only cost about 40$ or so, and the only thing I dont have is instructions.

Does anyone know how the proportioning valve would hook up to the system? and How many I would need?

I'm also a little bit confused as to its function...it says you can increase psi up to 1000 and reduce up to 57%. Does this mean that I can add more line pressure to the rear wheels thereby changing my brake bias? I wouldn't mind being able to give myself 70-30 front/rear braking.

2ndly, does anyone know how the linelock would connect up to the system as well? and where I might have to tap into in order to hook up an arming light?

The proportioning valve goes inline between the master cylinder and rear brakes. One line goes in, one goes out, so if you have TCS, then you'll need to tie the left and right side rear lines together to go to the prop valve. It's purpose is to limit the line pressure going to the rear brakes. If the rear brakes received full pressure, they'd lock up almost every time as the nose drops downward and weight is transferred off of the rear wheels. Using an adjustable valve allows you to adjust the brake bias, however there's no real indication of what the bias actually is other than the car's braking manners; so to say that the bias is set to "70-30" is really at best just a guess unless you have a pressure gauge on the line. This is the valve I have:

For the line lock, it will go inline between the master cylinder and the front brakes. Again, one in, one out, so if you've removed the ABS block, you'll need to tie the left and right lines together. For wiring, it's easy enough to find a ground in the engine bay. For an arming light, I use a rocker switch with a light in it. The switch passes 12V to the solenoid, and there is also a ground to the switch for the light.


While I haven't set my prop valve up yet, (probably will in the next few weeks though) I plan on trying to place it and the line lock directly on the master cylinder. I'll try to get some pics up when I do it.

Re: ABS delete and Line lock

that would be awesome...I have two lines going to each front brake, and one to the back I believe. It is a 96 so no TCS, only 2nd gear start....Im not sure though, how would you go about tieing the two front brake lines together? Would you use something like a "T" type block or something?

Correct, the two lines go into a T and a single line up to the line lock.

Re: ABS delete and Line lock

so what would happen to the extra line that would of gone to the master cylinder then?

Re: ABS delete and Line lock

There are 2 lines coming out of the master cylinder. With the ABS deleted and a line lock installed, the forward most line will go into your prop valve, then out to the rear brakes. The rear line will go into the line lock, then out to a T that splits to the left and right front brake.

Oh, ok got it...that T split shouldnt effect brake performance should it? And, I don't think I will need to run new brake lines...I should be ok byt cutting the brake lines a little higher, and just bending them to the T, then maybe just run a new piece from the T and proportioning valve to the master right?

Re: ABS delete and Line lock

Correct, sort of... The new line from the T will run to the line lock, then up to the master.

The T will not affect brake performance, as it's essentially what the ABS module was doing... it was just a much fancier T. ;)

Re: ABS delete and Line lock

ok...lastly (for now) where could I buy a "T" block that would work for this?

I bought mine at the home depot. After installing the proportioning valve I found out I did not need one. It is fully opened and works fine you might want to leave it out and save yourself some money. I did have a line lock on the car also and later took it off. If you want it $5 and it's yours (Jeg's brand).

Re: ABS delete and Line lock

Looking at installing this line lock now, but I got a few questions.

1) What controls the proportioning of the brakes? Is it essential that I get that proportioning valve so that My rear most brakes do not apply as much pressure as the fronts and lock up everytime I stop?

2) the picture posted in the link above (and blown up below this)...is it not backwards? As stated above, I thought that the single line from the "T" goes into the "out" slot of the line lock, and then the line from the "in" goes into the master cylinder? And then I just need a straight piece to link the rear most line from the master cylinder to the brakes?
The picture looks as if the line lock is hooked into the rear brakes?

Re: ABS delete and Line lock

In this picture I don't see a line lock, only the proportioning valve. The two lines going into the T are going down to the front brakes. The Jegs block is a proportioning valve, and goes back to the rear brakes.

Also, I noticed a mistake one of my previous posts. I stated that the line to the line lock comes from the forward most outlet of the master cylinder and the proportioning valve goes to the rearward most outlet of the master. This is backwards. The front brakes (line lock) come out of the rearward most outlet and the rear brakes come out of the forward most outlet. Although I guess if you were replacing all the lines, it wouldn't make a difference. I corrected my mistake in the earlier post.

Thanks, I was actually relying on that info, so good thing you told me. I'm not sure if it makes a difference? What is it in our brakes that controls brake propotioning...is it in the master cylinder? or was it in the abs module?...if I delete that abs module should I be getting a proportioning valve?

I also thought that jegs thing was the line lock, thats what confused me as well...

Re: ABS delete and Line lock

Yes and No, I dont wanna spend that kinda money...I have a line lock, just need to know if I need to get a proportioning valve in order to make the rear not brake 50/50 with the front...
