01 zr2 abs pulses on light braking, such as coming up to a stop sign. Not really sure what it is, as I have only had the truck for about a month. It's kinda dangerous though, as I have almost slid into people in drive thrus, slid out into oncoming traffic from a side street, ect... The ABS module pulses a lot during light braking, which I can feel in the pedal, and sounds almost like a metal grinding noise. Can't seem to find an answer for it, and I don't wanna go dropping a couple hundred dollars on a new ABS module if there's something else that can be done to fix it. Any help would be greatly appreciated.
