disconnect 97 Blazer ABS system

tazrock · 01-06-2005, 08:38 AM

I have a 97 Blazer, and the ABS light has been going on and off for the last 2 months. When the light is on, the ABS does not work. But sometimes the light goes off, and the brake pedal gets very hard to push and the braking is very hard and dangerous.

I have realized that the ABS system for the 97 blazer is very poor (to be polite) and prefer having the non ABS brakes.

So I am looking at the simplest way to disconnect the ABS system. I have tried removing the fuse, but realized that it shares the same fuse as the cruse control. I could rewire it to be one its own.

Any other idea?

Thanks

I can sympathize with that problem. Same thing here. I am used to driving the truck when the ABS light is on. However now its snowing in the ABS light goes off and it starts working at the worst times. i.e. when its very slippery. If you find out how to cripple it let me know too.

Not a smart thing to do guys, your system is designed for ABS and cannot be miraculously switch back to standard brakes.

Has anyone put the effort into actually checking out what the codes are stored?

The code on mine is a Front Right Sensor Malfunction. Escentially its Dirty and same rust has gotten caught up in it. I cleaned it once and the Light stayed off for about a week now its back on and off again. I Personally would have purchased the truck with no ABS system at all if it was an option.

I'm not sure how your insurance companies would react if you were to disable the abs and you were invloved in an accident but if your use was on a farm or to drag race, ect...here's a sight to check out...

The Vehicle speed sensors are the usual culprit of the ABS problems.

A simple cleaning and reinstallation will usually clear it all up.

The 97 blazers are known for there very poor ABS system, check-out any used vehicle magazine.

After driving without ABS for the last 2 months in the snow and ice, it is very clear why. (I suggest you try it for a few days)

I think I rather take my chances with my foot than the ABS system.

But I understand the possible insurance and safety concerns. I had talked to a service guy at GM and he said legally he can't disconnect it.

Thanks guys for you feedback, I might give it another try and clean the sensors.

You guys that want to turn off the ABS system and you even get into a little fender bender had better pray to what ever God you pray to that the person you hit does not get a good lawyer because if they do you will be in deep dog doooo.

Exactly.

This system is designed for ABS ONLY.

Don't fuck with it, it will kill you or someone else.

To add a little more to what Fireplug has said. You more than likely get a reduction in your insurance premium for having ABS. I know I do. You would be removing a safety device and there may very well be a clause in your policy that will make it null and void. Here comes that lawyer.

I don't quite agree that it is design for ABS only.

ABS assists your vehicles braking, it does not replace it.

So when that system does not work properly, and GM is too cheap to have a recall, but changes it in the 98 models, you have to ask yourself some questions.

I agree with this statement. If your ABS fails, your Hydraulic brakes still work. The ABS is an Electro-Mechanical assist system. (In a driveway away from any moving traffic, remove the electrical connector to the ABS unit, and see if your truck stops)

I also agree with other posters stating don't screw with it. With all the other weird things going on with these Blazers, who knows what might happen.

Now for some levity, my personal opinion, somehow the ABS is linked to the bad wiper pulse board. While the bad board will not allow the wipers to work when it rains, the ABS senses a wet surface and will not allow the truck to stop. I've had this problem since day 1, The ABS is HIGHLY SENSITIVE.

Look, if the ABS is not functioning properly, you need to have it looked at and repaired...this is an enhancement to a safety item.
I highly recommend that you have a professional diagnose the problem...there are too many liability issues involved with operating a vehicle with a know problem or disabled safety system....

ABS has been proven to reduce the stopping distance in panic stops, it prevents the tires from looking up and loosing traction..there is no way, you as a driver can do a better job

BULLSHIT!!!!!!!!!!!!
These two systems are seperate and share nothing in common with the operating systems.
ABS only sees that a tires speed is different than the rest (indicating a skid) and activates the system...it does not sense weather conditions only wheel speed and brake apply

I love the conspiracy theories

tazrock · 01-07-2005, 12:23 PM

I thought the same thing as you, that it is an enhancement to the braking and "should do a better job".

That is until the system stopped working and I went back to the good old fashion braking. I can definitely do a better job! I know what is in front of me and how far away it is, as well as what the surface under my tires is. The system will definitely help most people, who have no idea of how to pump the brakes manually in emergency situations.

As I previously posted, try it for a few days, I am sure you will agree.

Maybe the system on other vehicle or the newer Blazers is better? But I am very unimpressed with mine.

BlazerLT · 01-07-2005, 12:57 PM

Sea , I'm sure you can cycle the brake pedal 50-60 times a second.

Only a moron will think that he can brake better that an ABS system.
