Last fall my rear brake pads looked great. This past week I noticed a scratching sound from my left rear brakes. I know this is the wear indicator, but I was surpriaed it came so soon. I removed the tire and found the inside pad ( one against the piston ) to essentially gone while the outside pad was still about half life. Have not seen anything on here about rear caliper problems only front. I am not sure it is seized, but it has to be dragging a little. Have a new caliper along with rotors and pads for both sides on order from Oreilly auto.
