@lorrie do you know if your front sliders have rubbers on them? 2014 they do. the rubber can swell and cause the problem you are having. Also the pads can be reversed not willingly (outer on the inner and oner on the outer) this might ave bent a slider pin witch could cause the problem you are having. Good luck. If you are close to Nashville I am not scared to look at it. I would think 2013 would be the same slide pin as 2014. There also can be a build up of rust on the pad hanger not likely your problem. It normally will cause uneven pad and warping rotors.
And all the stuff FTO said should be checked if the mechanical seams to be good. Might be on the fluid side. Hope this helps.
