I've working on putting an 18in custom front wheel on my '04 Electra Glide which has factory dual disc on the front with an 11/16 bore chrome master cylinder. I want to change it to a single disc with the new wheel so the wheel is not completly covered by rotors. HD list a 9/16 bore master cylinder for their bikes with a single front disc and the 11/16 is for dual disc. Can I use my 11/16 mc with a single disc or will it push the seals out of the caliper from to much pressure?? I just put the chrome conrtols on the bike about 10 months ago and hate to have to buy another 200.00 mc if I don't have too. I'm hoping I can just run a new line from the cylinder down to the single caliper and eliminate the distribution tee under the lower tree. Has anyone done this or know if this will work?? Thanks!!
