has anyone ever considered deleting the abs system? would there be any advantage at all? what would need to be modified?

You could pull the fuse but you would lose ABS, magnasteer, and TC. You can not disingage just one permanently without loosing the other two. Also, the light would stay on until you removed the dash to pull it.

My sending unit went a while ago. Whithout it, neither the ABS of TC work. So now the car basically drives with normal brakes. I don't mind it. The only thing is that the lights for the ABS and TC stayed on, so I pulled the panel at the side of the dash where you access the fuses and there, you can also access the light bulbs for the ABS and TC, they twist out.

driving without the magnasteer would stiffen up steering? i cant say if i ever noticed a difference with t/c and without?

Why get rid of ABS? Do you want to make longer stops?

Deleting the ABS would involve a lot of plumbing. The ABS controller also acts as your distribution block and metering for the front/rear difference. It's certainly do-able. But you are better off just to unplug the connector at the ABS.

That said, a working ABS system is just standard these days. If it's not there and somebody drives your car who is expecting it to be there, there could be big problems, and YOU _could_ be held accountable.

Technically you can make shorter stops without ABS, but with any kind of skid you can lose control, that's the point of ABS so that you can still STEER in a panic stop situation. Why wouldn't you want that?

I don't believe you would have to change boosters.
I had a 95 Chevy blazer with ABS and the ABS control unit went bad and tripped the light. All I did to that was disconnect one of the wiring connectors going to the unit (there were 2 ) and killed the light and continued driving it that way for a few years before giving the truck to my brother. I told him about it and he hasn't fixed it either.
Had no effect on braking other than the loss of ABS. Also saved money on not having to repair some bad wheel speed sensors, as the only function they had on that vehicle was to feed info to the ABS only.
On the Riv the wheel speed sensors also feed data to the Traction Control.
The Riv has proportioning valves separate from the ABS unit. They are located in the brake lines going to the rear brakes.
I don't know if just disconnecting the wiring will kill the light on the Riviera like it did on the Blazer though. You might want to try that first to see what happens and look at the wiring diagram to figure it out.
The rest of the job might be as simple as just eliminating the ABS control Unit and re-plumbing some brake lines. I don't know if it's just that simple or if there are other repercussions in doing this mod. Try at your own risk.
You did say you have read something somewhere about the delete, maybe that source has some more answers.

yeah. a ase certified buddy told me that the booster would need to be changed and the master cylinder. this was several years ago that he told me this so i might have that one wrong. could be just the M/C needs changeing.. what im looking for is a really clean engine compartment. i want to do away with all the clutter that i can. allready the bay is looking cleaner with the cruise gone and the modified throttle bracket cut down and the power steer res moved over to the alt side. i can get at most anything now with the engine the way it is. i have a clean shot at the rear plugs and i can even get the rear ex manifold out from the top no prob. getting rid of the abs sys will make it that much cleaner. and vegas is mighty dry so im not worried about stopping in the wet. and these days i drive like my granny.

I personally don't see why either the vacuum booster or master cylinder would need replacing.
The master cylinder bore diameter of any vehicle is determined by the size of the caliper and/or wheel cylinder bore size. Basic calculation of the volume of fluid that is needed in the system. You are not changing either of those, so again i don't see why you would have to change the master cylinder.
As far as the Booster goes, the diameter of the internal diaphragm is determined by the amount of assist needed. This is determined at the design phase of the complete system by engineering.
I would leave the stock one in the car and see how it feels after removing the ABS Control Unit. My GUESS is that it will be fine, if not then you can determine if you need a larger or smaller booster.
There won't be any emergent need to change it in my opinion.

Can we get a pic of the engine bay? Sounds interesting.

when i buyed my car. the abs and tc did not work cos one sensor was broken.
so i drived allmost a year whitout them.
now they work but i guess when snow comes i will take teh fuse out or something.
abs actualy dos make stoping longer but it lets you controll the car stearing.

and i have better pedal feel.

well who have been used whit it can keep it but whit the experience what i have i rather drive in slippery condisions whitout it. dont want any computer or w/e start to help me.

one one brand new work car i pulled off all the fuses for abs, traction controll and so on. cos of that stoopit traction controll what started to stop the cars wheels of spinning in snow/mud when one wheel was goign to start spinn freely....the system just breaked teh wheels and made me get stuck.


only time i guess when its good is on higher speeds +30miph

A few more items can be removed to clean up the engine bay. The blower can be removed and replaced with a steel plate. The engine is surprisingly strong without a supercharger. Hood struts always get in the way, so take those off and use a broom handle to prop. Hood insulation adds weight and collects heat around the engine, so toss it. The intake tube and air box take up the entire front corner. Just remove all of it right up to the throttle body - the TB screen will keep rocks and leaves out of the engine.

Hey, I'm just trying to help "uncomplicate things", getting rid of tons of crap!

Come on... ABS and cruise control? Are you serious? This reminds me of pulling head lamps for cooler intake air.

The normally mild mannered AA was found today kneeling and laughing uncontrollably amidst the battered and hacked shrapnel that until yesterday was his pride and joy, his car, a much sought after and prized rare example of a 1998 Buick Riviera, with super charger! After the local authorities managed to calm him down they asked him " why did you do it?" the once model citizen from c-bus ,ohio,could only respond in a shuttering and breathless voice "dat rr.oo.b..bbo.t.t.t. ten.n.ni.ss   i. i i..imm  go..n..n..a..a  k.k..k..ii.ll   him! " authorities are baffeled as to who this"robotennis might be? There is speculation that he might be the king pin of a  drug ring responsible for the manufacture of a highly potent new drug derived from power steering fluid! of which traces were found on the crazed AA's breath,and ooozing from the once proud grill of this beautiful car. The cars next of kin have been notified but so far none have come forth. A car going by the name of "found-on-road-daily- claimed to be related but could not show proof of that to the authorities . The residents of c-bus ohio are startled and saddened by these unusual turn of events and send their prayers out to double AA's family......

So, IF you go ahead and follow thru with this plan of yours, would you change it all back to stock if you needed to sell the car?
