Today my left front brake started to make a bit of a squealing/dragging sound when not braking. I replaced the pads 70k back and thought they might be due, but when I popped the wheel this afternoon I saw that I still have approx. 1/4" of pad left. Last time I did pads I remember them being much thinner. I felt some resistance when turning the wheel by hand. It seems to me like more than just dust. Any thoughts?

Back in the West!
