I recently had the brake pads replaced on my 2001 Silverado. The
brakes work fine except for the ABS feature. The ABS kicks in at low
speeds on dry non-slippery surfaces, making it difficult to stop at
low speeds. They work fine above 2-3 mph. What could cause this. I
believe the ABS sensors are fixed in the hubs, and that I have to
replace the hubs to replace the sensors.

You probably need to remove the speed sensors and clean the
mounting surface at the wheel bearing. There have been problems
with the front sensors lifting away from their mounting surface due
to rust and this causes the signal to drop out at low speeds.

I think there may be a TSB on this. I assume you're out of warranty?
