So, trying to finish pad change before dark, and when compressing the outside piston to insert the new pad, the inside piston fully extended (forgot to leave old pad in).

Now I can't compress the piston to insert the backside pad.

I'm guessing that I need to rotate the piston, but wanted to ping the forum to see if that is what it takes to get the piston compressed.

Thanks for the help.

 

I had this happen to my project car (not an LS) on my way to Va, ate the rotor up and it shot out of the rear of my car.
