Two problems related to brake antilock wheel speed sensor have been reported for the 1999 Chevrolet C1500. The most recently reported issues are listed below.
Many complaints with this vehicle may get long but I am not sure as where to send them all. #1 window regulator failed three times, the first time I had to pay the full amount to get it fixed as the company recommended by the dealer went bankrupt before the warranty was up, I was never contacted about this. #2 broke two more, times dealer picked up cost on the second time but not on the third time the window is taped up as the dealer said they won't fix it as the 1 year warranty was up. Anti lock sensor was only cleaned and is still acting up truck lurches after stops. Dealer said that they probably won't do anything as they already cleaned the sensors. The truck was purchased used and I did not notice the bed on the truck had been repaired. It looks like it sits a little lower now on one side the service rep said there were spot welds where there shouldn't be but wouldn't comment beyond that.
Hydraulic brakes problem 09/04 brake pedal is very stiff at low speeds. This causes extended stopping distance. A mechanic friend states it is the speed sensor in the anti-lock brake system. No warning. Happens in any conditions. Intermittent, happens under normal braking conditions. Permanent. Can't depress, the consumer must pump the brakes when attempting to stop at lows speeds. The brakes have serviced regularly as well as the vehicle.
