99 A6 Avant quattro w/ about 60k miles.

I just put new pads and rotors on the front. Gotgerman pads (Pagid) w/ the sensors, and Zimmerman rotors. Took it around the neighborhood and the right side was squeaking as if the pads were dragging. A few times the pedal would vibrate as if the abs were kicking in, this under light breaking. Took it back apart, made sure the slide pins were lubed well so the caliper would center itself, still squeaks. A buddy suggested swapping the pads to the other side to see if the noise would follow. Tried this, still squeaks on the same side, and now the pedal vibrates bad, like the abs is kicking in every time I step on the pedal.

No brake or abs lights on the dash, seems to stop straight. The only thing I can think is the rotor may be warped-? Any ideas?

 

air in the system, bleed the breaks

 

I never opened the system,not sure how air could have gotten in. I'll try it though.

 

quite simple really ( you compress the piston in ) then air is drawn in because the seals are aged but still ok, just bleed them and see

 

bleed both front not just one side

 

Well, I bled the brakes and went for a drive. The vibrating pedal issue stopped after a couple stops, the squeaking is getting better, maybe it will go away as the pads wear in a bit, but now the ABS light is on. It stops fine, the pedal is firm, everything seems to be ok, but now this ABS light- ?
