After putting in the Throttle/Brake quadrant I filled an leak checked the brakes. I had to make a small mod on the threaded portion of the piston to allow full freedom of movement. There was not enough movement to allow the piston to the full extension and I was concerned there may be pressure to the brakes which could result in dragging. A 1/4 inch was removed and full freedom was noted. Brakes were set and checked next day for leaks.
