Some interesting notes from the brake job:

One brake pad (outside driver side) was completely worn out and was the culprit for gouging into the rotor. One was a little more worn on one end but still had plenty left and the other two had at least 50% pad left. It seems like I had a stuck caliper, otherwise, the factory pads would have easily lasted another 30-40K if not more. This is one of those unforseen and unfortunate $350 expense.

In hindsight, what is more interesting is that a year or so ago, my gas mileage dropped from 300 miles per tank to ~260-270 miles per tank quite instantly. At that time, I never really considered a stuck caliper as a possible cause (didn't really feel it much) and other things like old O2 sensors, spark plugs, EGR, clogged fuel filter, etc. seemed much better explanation. But now looking back, it was due to the stuck caliper on the outer driver side. The lower mileage was just another cost of this ordeal. So if your mileage drops suddenly without reason, make sure to also check for a stuck caliper
