i think we found our problem, its hard to get every last bit of water out of a pad after washing it especially microfiber. i know with the hydrotech pads if you have alittle bit of water in them they heat up the pad alot more and are more prone to failure, so it would have been better to switch pads and let the one you washed dry out, or it could have been using the makita to spin dry it. as we don't use the highest speed on a makita ever to polish a car so that high amount of centrifugal force could have weakened the glue or something of that nature, wait until chris@optimum chimes in again. my guess is it was from the pad having some moisture in it or the high speed drying after washing it....i would never spin dry any pad at the highest speed i would spin dry at 1000-1500 rpm, remember the best washing machines out spin dry at 1000 rpm. when a pad is spinning at a high rpm it can stretch out and exceed its limits, give the pads another try and don't exceed manufacturers recommended rpm range for anything you do.
