    Default ABS Issues?

    I'm just wondering if anyone else has run into any issues with their GM abs systems. My 2 brothers and I all own GM products and we all have taken out the abs fuse in our trucks. The problem was that the abs always kicked on, even in the middle of summer on dry pavement and in the winter it was a nightmare my truck was like the energizer bunny it just kept going and going. The vehicles with issue were a 97 Silverado 1500, 03 Silverado 1500, 03 Silverado 3500, 03 Sierra 3500, 00 S10, and an 03 Suburban. Normally I would think the problem is just mine, but since we all had problems, I didnt know if we were the only ones.

    I have a 96 Z71 and i have the same issue. I have been trying to figure out the cause but have had no success. The only thing i can even come close to is that i did have a brake line go out on me, maybe there is air in the abs that i cant get out without a scantool for abs.

    If the ABS just kicks on for no reason then you may want to check for mud, debris, or bent wheel speed sensors. The reason the ABS kicks on and rattles your foot is because the computer "thinks" one or more of your wheels is turning at a different speed than the other wheels.

    I have ABS Issues with my 99 Silverado also. I have Ramdomly replaced the ABS computer & all the sensors. That wasnt cheap because the sensors are "built into" the front Hub Ass. & I had to buy both @ 300 each!!! Still same problem. Mechanic says it needs a new computer AGAIN!!

    Mine had the same problem... luckily under a 30 day / 1000 mile warrenty. Wheel sensors didn't fix the problem so it went bad just a day later and the ABS module (computer) was replaced at about $800. After it was replaced, the added boost from the new module blew every brake line in the truck. Needless to say I bet the dealership lost money on the truck after doing all that work.

    My work has 4 Chevy vans... 3 1ton SRW and 1 1ton DRW... 04's and 06's. they all have had ABS issues, multple times each in fact. Seems as though Chevy trucks are plagued by a poorly designed braking system.

    If I pull my ABS fuse, will it turn the ABS light on.? With the fuse pulled does it have any effect on the braking abilities.? This is on my 99 GMC K3500 Dually. I pull a trailer and don't need any more surprises...
