1998 chevy express van 3500 front brakes and rear are new, front calipers are new but ABS light on dash is on, the front brakes smoke after a little while of driving. Thanks Joe

My 1998 Express van brakes started smoking recently too.
I changed the brake hoses and the smoking stopped

Bit worried about the smoke...indicates pads being in contact with the rotor. Make sure that system is completely clear of air bubbles. The ABS light is actually unrelated to brake condition. The ABS system (and traction control) make use of the speed sensor on the output shaft of the transmission and further speed sensors on the individual wheel hubs. The ABS system monitors the signals from the all the sensors. If any one wheel runs much slower than the others when braking is applied the ABS system relieves brake fluid pressure to the caliper on that wheel. The speed sensors consist of magnetic devices detecting the teeth of the reluctor rings on each wheel hub and on the transmission output shaft. If a sensor is at fault or a reluctor ring is corroded, dirty or split then this causes the ABS light to come on. Check all the wiring to the sensors and that all connections are clean and bright. Next check the hub reluctor rings.

I'd first make sure the new pads are the correct size. Doesn't happen very often but maybe the parts person gave you the wrong size pads ( for the smoking problem). As for the ABS light, most newer cars will throw out codes if you wait too long to change them out, I would contact a chevy dealer or search online about reseting the code (light).
