Hello everyone. This is my first brake change and the very first caliper I was working on I messed up on. I was using wired to retract the piston and went in the wrong direction until in came out.

I then bought the obdeleven and did 2 other brakes completely. I came back to the rear passenger side to reinsert the auger bolt and piston but the bolt will not screw onto the bolt inside the caliper.
