this is about my wife's (GMC, 97, 1500, 4x4, 5. 7, auto, ext. cab) it has approx. 56k on it. the problem is when she is in the final stages of stopping her brakes will do a skip like she is starting to slide but it only releases once and grabs right away. sometimes it will do a little more where it lurches forward 6". we have taken it to several garages and they cant find what it is. they say it happens too fast to show a code. can anybody help us with this or any suggestions for possible gmc site that is as well educated as TDR.
however one of the garages has tried to check the four wheel sensors and it has come up empty handed.
p. s. there is ctd in the future for her, if she can behave herself. but for now we need to fix the gmc problem.
