I needed this for my 2017 Buick Lacross for my rear screw in piston(not push in)type pistons. It adjusts and has a two pin side and a three pin side. Mine is three pin. You can adjust circumference and you must apply pressure to keep pins in place as you rachet right to get piston back in. Be patient and it will serve your need.
