Any scoring on the rotor? If it's debris stuck on the pad or at the edge of the caliper, taking the wheel off won't help, but you might see it scratching lines in the rotor face. I have had that happen to me before. Usually going in reverse pops it right out, but I suppose it could be really in there. Did you ever check the CV boot?
Checked the boot and it appeared to be fine, no rips or anything else that looked out of the ordinary.I've not had the wheels off mine to look, but.. do these have a metal dust shield on the inside?
I've had a stone get hung up between the rotor and dust shield MANY times on other vehicles. You wouldn't see it unless you took the caliper off to take the rotor off...
I got good at getting them out by tapping on the edge of the shield with a wooden drift and mallet, gently-ish.
ETA: Oh yeah, it's not the wear indicators on the pads, right? (Do these pads have wear indicators?)
I used to do a lot of canyon driving and the car is a little over 30k miles so I figured it's possible it could be the pads/rotors. The rotor looks like it has some minor scoring, feels completely smooth to the touch, but if the brakes are the culprit wouldn't I notice it more-so during braking? It's quiet under braking, still bites strong, and I don't feel any vibrations in the pedal
