How do I fix the anti-skid brake system on my '98 Sunfire? It's way to sensitive!?

Question

I understand it may need to be brought to a shop, but can anyone lead me in the right direction?
Thanks,
Vince

Answer 1

some times thay are very sensitve but to start check your front suspension especially struts if tires bounc it wil set it off. if no problem is found remove the abs fuse(s) test drive the car and make several hard stops if the brakes lock up unevenly or pull hard while braking the prob. is in base brake system. repair as necasary retest then replace fuse and see if change.if tou can,t find problem take it to a shop somtimes intrmittant speed sensor can cause this

Am I understanding the question is how to make the ABS not react when it is not necessary? If that is the question you have no hope as the system you get is the way it is. Some of these ABS systems react when going over bumps while braking. All the ABS is doing is reading the speed of each of the wheels and comparing it to all the others. When there is a difference, the ABS thinks a brake skid is happening. The first thing to do is get the brakes inspected by someone who really knows what they are doing. Even a change in tire size affects the ABS, so that may be a problem. A lot of the cheaper or aftermarket brake pads and shoes do not have to proper coefficient of friction so that tends to have an effect on the whole braking system, like the ABS. The only thing you can do is to get the module scanned to see if there is a problem with it and the possible codes that will give you clues as to what is happening, but I suspect there is no codes as your question does not state the orange or red warning lights are coming on. The only solution left is to disable the ABS which will leave you with power brakes but no ABS at all. I suggest you learn how to drive the car without setting off the ABS. That sounds stupid, but you now know what is setting off the unit, so those tips can lead you to alter your driving pattern. Maybe??? Good luck.

Technically, your question should be listed under Pontiac, not GMC. However...

Unless you're a trained, licensed mechanic, it's best to leave brake work to the professionals. First, take the vehicle to the dealership. Sometimes they will make a simple adjustment and charge you little or nothing (they like to keep their customers alive so they'll come back and buy a new car periodically).

If you insist on doing it yourself, then you can buy a repair manual for your vehicle at this site for just under $30. That way, you not only get this job done, but will have it on hand for future repairs...

If you don't want to pay shipping and don't want to wait, you can look for a new Chilton's repair manual at nearly any auto parts store. If they don't have it in stock, they can usually order one for you that you can pick up in a day or two, depending on thier supply delivery schedule; certainly not longer than a week.
If you don't want to plunk down the cash for your own copy of a manual, check out your local library and see if they have one to borrow, or copy from...

In any case, look for Chilton's repair manual for your vehicle. I find their manuals to be the easiest to work from; better organised, better illustrations, and clear step by step instructions and safety tips on ticklish tasks.
