Disc pads dragging on rotors
I bought rebuild kits. But after i made sure calipers and pistons were not pitted. A quick cleaning, blast, hone, high heat paint. And reassembled. I think it was better off than cheap rebuilds of suspected crappy quality. That way I know the bodies and pistons condition versus unknown rebuilds. Once your good cores are gone they are gone.
If yiu have Amazon these are good cheap pads.
