I have never suffered this problem, I think there is a strong temptation to use excessive pressure instead of letting the tool do the work once the performance of pads drop off change the pad. Maybe a good scrub with a wire brush might rejuvenate them for a while. They can be expensive to buy anything from 20p to 95p each for a 125mm and the price does not reflect quality. I use 60,80 and 120 preferably ceramic as they stay sharp longer (evidently grinding metal sharpens them).
