Does the upper smaller bore connect to the front or rear brakes. I have a 1976 (transition year) canadian mini 1000 and am in the process of replacing the master brake cylinder but the instructions don't seem to match properly with what I have. To complicate things I have just done a disk brake conversion on the front and want to make sure I have the brake lines hooked up right. If anyone can shed some light on this It would be much appreciated. Thanks
