I recently took my font and rear wheels off to get new tires on my 2014. I noticed the brakes on the front rubbing slightly when I put it all back together. I don't recall this being the case before. I know when I used to change pads on my disk brakes on my mountain bike, I had to slightly align the caliper on the mounts so it wouldn't rub. What is the possible reason here? I made sure I did not squeeze the levers with the wheels off. It's ever so slight but definitely has my attention. Will it go away as the pads wear or do I need to address it?
