the vibration problem,  if it is not a severe abs pulse-like problem,
is probably just warped rotors as someone previously posted.  have had
this problem w/ everything from volvos to explorers if either the
prior brake job didn't include cutting the rotors (if they can be cut)
or the rotors need replacing.  my ev w/52k also vibrates (non abs) and
the prior owner just replaced the pads.  i will try cutting then move
on to replacing w/ cross drilled rotors.
