I should do a video on this. I have the best method for brake pads with the rotor.But I do not understand adjusting the concentric on these calipers after a seal rebuild and new pads.

This, precisely, is the correct technique. Now, if I can make a really bad video demonstration, I will post it here.Basically, I apply a small amount of brake pressure and then turn the eccentric one way until I feel resistance, then back the other direction to find resistance. I can then figure out where the center is when the pads are parallel to the rotor.
Anyone have a link to a rebuild video for the R90S from brake system? I have a weeping caliper on a 20 year old rebuild. Good clean brake fluid. Probably just time for seals.

Actually, you want the inside pad (wheel side) perfectly aligned/flat/flush with the rotor. The inside pad is fixed/immovable and must fit flat against the rotor. The outside pad (piston side) is somewhat "flexible" in that it will self-align to the fixed inside pad. Kurt's alignment procedure described above is the easiest and best way to to adjust the caliper.The eccentric pin rotates the caliper(s) so the piston side pad is perfectly aligned with the rotor.
