OK I replaced the pads rotors calipers and brakelines on my car. I unfortunately let the master cylinder drain dry. The car was on stands for over a month while I got parts. Well after I bled the brakes and clutch the ABS light stays on. The brakes are fine with excellent pedal feel. I've heard stories about letting the master cylinder drain out and I don't have those problems. Also If I don't have a ABS sensor in position(bolted in place on the knuckle) will this set off the light? Thanks Tony
