otherwise, there is a TSB out for a similar situation. The ABS will kick in at extremely low speeds, like when you're pulling up to the end of a parking space and trying to stop. Either the front wheel bearings can be worn/loose or rust builds up behind the wheel speed sensor and pushes it out of the hub assy. making it not always read the reluctor ring at low speeds. I believe the TSB only lists newer trucks (99-04) but I've seen the same condition on older ones also.

Like others on all the sites the same problem soft peddle . I've bled them 2x power myself then had my son pump bleed them no change. took it to a mechanic he power bled them same result. took the truck to a former GM mechanic he coulden't find any thing wrong but thought it might be the rubber lines balooning. Had him change them and re bleed the lines same result $380.00. took it to to a well known safety center he checked it out and everything looked good . power bled w/diognostic tool to cycle abs module while bleeding. He thinks it might be the ABS module $780 + labor maybe will fix it. NOT HAPPINING . $1300. later 98 silverado 4x4 is now a ranch truck.and new K2500 in driveway. I'm not gonna kill some inocent family w/ lousy brakes. WHERES THE MECHANICS THEY ARE ALL PARTS CHANGERS !!!!! Glad I got that off my chest I feel better

I don't have soft brakes as I mentioned in my earlier post, but I did have a dang ABS issue where it would go off as I was stopping at slow speeds. I replaced all the front end brakes, Bled them professionally and blew out the senors, There was NO ABS light on in the cabin. After doing all this the ABS sensors would only act up on the very last couple of inches while stopping. Instead of replacing the ABS module, I simply took out the 60 amp fuse to the whole module under the hood. So basically I am driving a 1987 GMC instead of a '97. The brakes work perfect because they are now manual. When I go in for a sticker this year I will simply replace the fuse for the inspection, and then out again it comes! * Drives and looks like new, but I;ll be D*mned to be spending more money on bad design, failed system for a 97 GMC with 130K. I realize I can probably replace sensors and it may or may not fix the problem, but to be totally honest, I enjoy the feeling of brakes without ABS! * I hope this helps someone with the same issues.

How can I check if the abs module is bad?

Hey guys here is what i did. I called the first brake repair shop in the yellow pages and got a guy that jumped through hoops and called a GMC dealer in the area. called me back and set me up.I took it to the Dealer and the service rep put two guys that own a 97-98 respectavly. they totaly checked it out and bled the antilock module and they are alot better. they stop slow-fast but still have a soft feel. According to them they are good no mechanical problems. The moral is bit the bullitt and take it to someone that knows and has all the tools to do it right . cost $125.00 half of what I payed each of the PARTS CHANGERS!!!!!!!!! Equinox and 2500HD going to concord Ca for service thanks Brian ps I was told that the module usually isn't bad unless you are pulling a code or ABS light is on

Thanks everyone for posting on this topic. It's been very helpful.

A coworker had a 1999 Suburban which had the weird ABS issue right as he was stopping. Turned out one of the sensor cables on the front right was damaged. Replaced and it works.

My current issue is a 1997 C1500 who's ABS light keeps coming on intermittently and it has the soft brake petal. When stopped you can just push it easily to the floor. When braking it doesn't stiffen up much, back brakes will lock up but I don't feel much from the front and the ABS isn't kicking in. I know it won't when the light is on since it's detecting an issue.
