It is fine during high speed braking. It only seems to make noise right when I let off the brake pedal at very low speeds as when stopping. It makes a very low frequency "pop" sound as I let off the pedal. It does not sound like a pad problem as there is no squealing.

The only thing I did recently was installed speed bleeders, bled the lines, and installed 17' winter wheels. The MC did accidentally go dry (i was looking from the driver side and not from the front and was staring at a full clutch fluid level). I bled the MC and everything seems fine regarding pressure.

FYI I did degrease and sand the wheel hub mounting surface already to no avail.

I'm thinking maybe it has something to do with air getting into the ABS system???
