Hi, can anyone help me? I am in a debate regarding the installation of the rear master cylinder on the brakes my wife´s 1979 Bonneville Special. When winding it into the casing, the instructions say you must only wind it clockwise. If you go past the mark and the grub screw does not line up, you must continue to wind clockwise and never ever go back. Another party says its okay to go back. Where can i get this info?
