I am having trouble diagnosing and fixing uneven rear brake pad wear. The inside pads wear even but the outside pads only make contact on the top half of the rotors. See the photos below.……. I have taken everything apart twice and put back together at proper torque and still am not having any luck making full contact. Steps taken so far……remove rear caliper, remove caliper bracket, remove guide pins, clean and clean guide pin holes, re-lube guide pins with sly-glide brake lube. Clean caliper bracket and pad clips with brake clean and wire brush. Retract piston fully, reassemble and torque everything to factory specs. Caliper floats easily on pins and doesn’t bind. Flat edge on rotor shows they are flat and not miss-shaped…..Pads float freely in clips and show no sign of binding…….please help, anyone got any ideas?
Car has 14k miles.
The factory pads used to wear evenly, I changed out to G-loc R8 race pads for track day 4 weeks ago, drove for ~250miles and they wore like this, I had some family stuff come up and did not run on the track, the R8’s were too loud and dusty for street driving, so purchased the G-loc street pads and placed in the car, the Street pads wear the same way, 500 miles later they are still wearing unevenly, took apart again this week and reassembled after torquing and they still wearing unevenly this way.

I'm not sure about the brakes on our cars, but I do know that that front brake pads for my 2013 Raptor have an inside and outside pad for each side and were marked on the back of each pad.

Since the brakes have been replaced on your car, this could be something to look at. 🤷‍♂️
