Are you machining the rotors while they are still attached to the hubs?
0.010" run out will cause major pedal feel and steering feel issues. You
want to aim for 0.003" TIR. You also need to check and make sure your pads
are NOT wearing in a TAPER.

Subject: [Fot] Rotor runout
My pads were pulsing pretty bad at the last race so I had the rotors turned
at a shop I trust.
Upon reinstall today I found that I had 0.010" of runout on the passenger
side rotor. I repacked the bearings and I use the spacer kit which was setup
with about 0.0005" of play. I was curious so I measured the runout on the
uncle jack hub wheel flange and was surprised to find 0.003" of runout in
the hub.
On the driver's side, rotor was 0.003 and hub wheel flange was 0.0005".
Did my shop just do a horrible job turning the one rotor? What kind of
runout is spec for the uncle jack hubs? Is it possible that a wheel bearing
race has gone wonky on the passenger side hub to cause the whole hub
assemble to have the runout?
