Thanks! I actually haven't done the fronts yet...this is all for the rears lol! the clicking noise is only when I put on the brakes, and I can only hear it when I'm driving through a neighborhood or by a shoulder barrier on the side of the road like you said. It doesn't bother me much, I have no loss of braking power or anything kind of performance issue.
