[Fot] brake bias

>  Is .006 enough to cause sittuation 

I believe so, yes.  Usual limit is more like .002", measured at the same
distance from the edge.  IOW it doesn't matter if the edge is thinner than
the center, as long as the thickness is the same at a constant radius from
the hub.  But if the caliper has to follow that change in thickness as the
rotor turns, it will push fluid back and forth through the lines causing the
pulsation you observed.

Runout is less of a problem, since it just moves the pistons back and forth
(assuming a dual piston caliper) or the caliper body for a single piston
caliper.
