Brakes stickin after brake job

Sounds like the mystery is gradually getting solved. Pictures are always a great help when doing things by remote control.

To the OP, that cut cable and spring are part of the self adjust set up. It clicks the little ratchet wheel on the self adjust screw mechanism. You would think for all that was charged for this brake job they could have put in new hardware kits and replaced all those little hardware bits. Another good reason to do these jobs yourself.
