Let me start out with the fine details calipers are original and are not stuck or binding in any way. suspension is original with no leaks and I keep my tires torqued to the 100 ft lbs spec. I do switch from summer to winter rims as the seasons change. I try to not be hard on the brakes trying not to drag them but I don't slam on the brakes every time either. I also don't tow anything regularly maybe 3 times a year being 100 miles total towing distance. If i had to guess the max weight is 1200 lbs. I did changed the slide pins and rubber pieces on all the calipers a couple of times and the fluid when I did the brakes the first time. The rotors I have on now are ebc plain surface and pfc carbon metallic pads. When I do the brakes I do clean and lube everything and make sure it parts move freely chance hardware and check the hub for any rust jacking spots.
Here is my problem after two years, almost to the day, after a brake job (rotors and pads) the rotors are warped or warn unevenly causing a pulsating pedal and shaking steering wheel. In those two years I put about 20k miles on the car the pads are perfect with no uneven wear and more than 50% life left in them. This has happened every two years since 2013. basically every year I either have to replace the front or the rear rotors.
What I have noticed is the outer pad rotor surface is smooth on all 4 wheels looks great. The inner pad surface is not clean like the outer there is pad contact all the way across not deep groves but the surface is dull and rough kinda like the moon's surface. I did say earlier that pad thickness is even with no uneven wear or taper but the inner surface is not the way it should be. The inner pad contact surface looks just like the outer. The caliper pistons seem to move freely. the only thing I have found is the bottom slide pin on the front is slightly tighter than the top pin but it still slides easily with no binding.. I also checked the caliper for rust jacking found none and the pads moved freely in their slots.
Now this problem is getting even worse my front rotors are two years old and pulsating and the rears are 1 year old (with less than 15k miles) and pulsating. Every spring and fall when I chance my tires and rims over I visually inspect the brake system and this past fall everything was perfect now it's not. The brand of rotor and pad combo doesn't seem to make a difference. I have tried thermoquiets on brake performance slotted an dimpled rotors that combo didn't last but that could have been my fault. pfc brakes on the same brand but new rotors same problem and pfc pads on ebc rotors came problem. and this will be my third or fourth maybe even fifth (i have lost count) full set of rotors and pads.
My only idea now its that its something in the calipers and any other ideas would be greatly appreciated. I don't want to just replace pads and rotors just to replace them two years from now with the exact same problem. I also don't want to replace parts that are good for no reason when I could put the money into something that actually needs it.
Sorry for the really long post and Thank you in advance.
