FoMoCoSho the dust was not bad after the break in. The break in they recommend made some serious dust. I took off all 4 wheels, cleaned and polished before I put the brakes on, so the wheels were super clean prior to the kit be installed. I took them off after the break in and did the same thing, there was some serious dust. After that time the dust was no worse than original. I followed the break in procedure on the power stop site verbatim. The only issue I had was the chirpers*(auto correct got me) for the front pads did not work, so I cut them off.
