Toyota Repair: Abs light, brake caliper, cv joint

Question
After replacing front brake pads and boots on outer cv joint on my 1996 Avalon with 108k miles my abs light is on. I was surprised after the job the pedal did not come up as usual. I did compress the calipers without opening the system. I pulled on a sensor cable accidentally,  but I didn't think I pulled the wire out of sensor. Please tell me what I may have done and the best fix. Thank you.

Answer
This usually happens when one of the wheel speed sensor wires is stretched by letting the brake caliper drop, it's a very thin wire inside the insulation, whatever side wire you think was stretched is most likely causing this problem, the solution would be to replace that sensor.
