I put new rear brakes on my 2007 Mazda 3 GT this summer and replaced the calipers 2 years ago and replaced the parking brake cables this summer as well. I noticed the inboard pad is worn pretty bad compared the outer pad, I am thinking maybe the caliper pins didn't have enough lube? I lube twice a season in the spring and in the fall usually when switching tires and notice the grease that was there this summer was kind of still there on some pins but gone on the other pins. Can I put a heck of a lot of grease to make sure there is some there next time I take them apart? Or you can actually put too much which would be bad? I am not sure what I should do or what I am doing wrong. I also wash my car often with a hot water pressure washer since we use it to wash the fleet, could that be it? I don't sit on the wheel for 20 minutes with the nozzle, but I usually just go over it to rinse it then I wash it by hand.
