I went through 1 set of front rotors in a 1 yr and 3 month seem like short time so I thing cause of excessive wear is that at least my year car 2000 has rear brakes (drums) that do not self adjust when you back up so more then usual wear to front brakes as front usually wear more in general (rears ever 3 rd brake job)so to adjust brakes on my year car you must take back wheels off and adjust the star wheel until you get resistance when spinning drums. So you must adjust as need to make break wears even out i think. As for a fix I was thinking of drilling holes in back plate (thin protector) so I can access from behind with brake tool to adjust brakes without taking of wheels GRRRR also note some models around my year car mostly have coarse threaded lug nut it mean they must have a torque them down to 110 ft lbs which can make any brake job go off to a hard time unless you have an airhammer to remove them and they do make electric 110 v airhammers that are pretty good for backyard mechanics as i have used one and was very good, they also make a 12 v electric lug nut removerjust like air hammer style but don't know if it can remove that high a torqued nut GRRR ??
Istarted to feel pulsation in the pedal sometimes little and some times really bad, I asked to my mechanic friend and he recomended to replace both rotors and pads which I did and all of that pulsing is now in the past yet i still to replace the rear drums and shoes which I can do nine months or so latter that I knew when I told to my friend how the condition of everything was, I did measure the drums and shoes linings so I have a break before i have to do that.
