problem with caliper/wheel/?
Hello everybody. so i've been hearing a slight scraping noise coming from my passenger rear wheel for the past few weeks or so, and it has recently gotten louder. i've noticed more built-up brake dust on the inside of the wheel than the others. the caliper is pretty darn black as well, darker than the fronts and a good bit darker than the drivers rear caliper. when i press the brakes, it sounds like a slight grind, but i can't feel it in the brake pedal itself that much. i jacked up both sides and found out that it was harder to turn than the other (it was pretty hard anyway because of the diff?) so it seemed like the pass rear was harder to turn (the one with the suspected problem).
anybody have any ideas? its weird how there would be more brake dust and the caliper would be black. it seems like a caliper might be seized? any way to help or fix that? would cleaning it with brake parts cleaner, or anything at all help the problem? am i looking at a costly fix? maybe i need new brake pads? i'm driving 150 miles away to bethany beach on saturday...
