Sunds like sticky calipers,,, maybe lube the slides?
I just read on another forum that if silicone grease is not used on the sliders it will cause the small rubber boot seals to swell (as petroleum based moly greases which are to be used on the clips and backs/ends of the pads only is NOT compatible with rubber) and will turn the pin-caliper into a piston-caliper arrangement, so when the calipers heat up the trapped air inside the boots will push on the pin and gently press one of the pads on to the rotor. Over time one of the pads will subsequently wear more than the other. Now this sounds exactly what may have happened to me as my front inner pads are worn WAY more than the outers (2mm vs 7mm). Could the guy at the Mazda dealer who serviced my brakes at 15,000 km be so stupid as to use moly based brake grease on my caliper sliders instead of silicone grease. I'm starting to think so.
