ABS Unit

[ShaneL]

I have a '96 vette and am trying to install a line lock inside the passenger compartment where the ABS unit is. Does anyone know which lines go to the front brakes? I want to (preferably) hook it up to the lines coming from the master cylinder before the ABS unit. It would be helpful if I could have a pic to make it easier to see which lines need to be cut but if you can't get em it dosen't really matter. I have no room in the engine compartment at all so this is my only option. Has anyone done this before and are there any problems when doing it?

Thanks in advance,
Shane

I guess it won't help you any Shane, but here's what I did, after relocating my battery of course:

I'm still trying to get it straight in my head whether or not the ABS fuse should be pulled to disable the ABS unit to prevent it from dumping, or otherwise going through its paces. When I engage mine, I seem to be pushing the front even though the brakes should be locked.

Granted, this step hasn't been tried in a water box yet, just the street. :L

I heard somewhere that the brake pedal has to be depressed in order for the ABS unit to activate. I may be Ok to pull the fuse just for extra safety (shouldn't hurt anything). Do you know how much current the line lock requires to operare? I was going to chop up a lighter plug and add a push button switch to it so that when I want to use it all I will need to do is plug it in and push the button. When not in use I can store it in the compartment.

doh!

A quick search turned up this thread!

Yeah, but you can see where we're still a little confused. Jeff says the brake pedal must be depressed for the ABS to be active.

Not that I don't trust my good friend Jeff, but I've gotta find something that describes the function of the ABS and how it actually works.

If I get the Hurst roll controll and a Summit install kit along with Hurst's adapters Part # HUU-5671515 will I have most of what I need to install the line lock?

 

[Ken]

Yep. I used a TCI roll control device, along with a Hurst installation kit.

Thanks for all of the help, Ken. I should be getting the parts by next week. I'll be sure to post some picture of my install when it is complete.

Thanks again,
Shane

I agree Ken, having a written decription would help.. but Like I said, having my Line lock installed like yours on my 89 and my friend's 96 GS. you depress the brake, hold the Line Lock Switch, release the Brake and the front is locked and the ABS is not active.

Remember the ABS uses the wheel sensors to see if any lock up, but I still think the Brake needs to be applied to activate the ABS.

Everything is nearly complete now, the roll stop is in place (A little messy) and I expect to get the last of the parts that I ordered this evening. The Hurst adapter fittings that were supposed to go to the ABS unit were not the right size, I needed a 12mm x 1.0 the kit came with 10mm x 1.0. I just cut the line and added standard flare fittings and used a coupler to attach it to the hoses going to the line lock.

Hopefully my vacuum pump will come later today and I can bleed them and leak test it.

This may be interesting...Poor tires

I will post some pictures of the install later when I am at home. Just putting the finishing touches on it now.

Finally

Been out all week and just got a chance to take some pictures today.

This picture is of where I installed my Hurst Roll Control, behind the driver's seat in the ABS compartment.
As you can see I have made a cable that will allow me to plug the line lock in whenever I need it. The cable
tucks neatly inside and there is no evidence of any modification from the outside because nothing can be seen.

The next picture is of the fittings I used after I cut the existing lines and joined them with the new ones coming from the line lock.

The third and fourth pictures are of my attempts to remove the rubber left on the driveway after "Testing " the unit.
Muriatic Acid (aka Hydrochloric acid) works wonderfully on rust stains from your irrigation system as well. (Just a helpful home care tip)

Now why would you want to clean the stripes off? :L
