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...

Like you said, its probably the caliper. A new caliper isn't too expensive. Itll be around 70$ at your local parts store, with a core exchange. But the scraping might be because the seized caliper is just running that sides pad all the way down to medal, so changing the pads is a good idea too.

I went through the same thing on the same side a few months back. My caliper was fine, but the slider pins for it were seized up, so the caliper couldn't move like it's supposed to. Yours sounds a little more serious than mine though, because mine never got hot enough to turn the caliper black.

it turns out i needed new pads all around and new front rotors. i should have gotten the rear rotors, but i honestly could not afford it all. 760 dollars. i should've just waited and got the parts myself, but the disc was ground down A LOT. they resurfaced them and couldn't do the entire resurface job on the bad one, there's still a groove on the far outside of the disc from where something was digging in before.

the car isn't braking very well. it is a slow brake, and requires some good force to bring it to a halt quickly. is it the new rotors on the front and ceramic pads they put on?
