Yes I had the cube type of retracter and used a ratchet to turn in. I turned till it bottomed out. After put all together the piston would retract once the brake pedal was released causing a soft pedal even before taking off jack. The emergency also would not hold. Once the garage adjusted the piston every thing okay. They would not tell how they adjusted the piston to the pad depth. Do the notches for turning in have to be in any certain position? The left side worked okay it was the right side that left a gap between the piston and pads.
