Can anyone out there help? I have a W & W springer disc brake set up and I am using an early Harley, '72 thru '81, master cylinder, lever and switch gear. It doesn't work 'cos the bore on the master cylinder is 3/4" and the caliper requires 5/8" or smaller. Course I didn't know all this when I bought the controls 'natch. Does anyone know a clever trick to get this all to work or am I going to have to bite the bullet and buy the handlebar stuff all over? then maybe I could get out and ride it!
