ok it sounded good . American suspension trashed one leg got a very good price on new leg ,now duel disk cool .maybe not . new rim new rotors. now the brake lines my stock master cylinder looks to be to big 7/16 cant find a duel banjo bolt help would good at this point want the setup to work safely new hear thanks very much

 

Welcome to the forum.

What's the question?

 

do I need to change the master cylinder to 3/8 .what I hearing is 7/16 is to large (to much brake fluid) when I look for banjo bolt for duel all I find is 10mm or 3/8 no 7/16 Harley was no help . so how do I connect the brake lines. American suspension brake lines are ran internally just want to fit them to the master cylinder I was told I cant do that I need to used a 3/8 banjo bolt (new master cylinder 3/8 banjo bolt if true witch one) so is this true or bull 2003 softail master cylinder is stock

 

You need an 11/16 master cylinder for front dual disc. Stock is 9/16". I think the other size you are referring to is for the banjos. An 03 should have 7/16 banjos.

 

ok thank you so I do need a new MC my is 7/16 banjo so what year hopefully I can keep the electrical side (wires internal) THANKS

 

You are going to have questions I can understand. Wiring? For what? Brake light switch?

What year what? Master cylinder? Bagger master cylinder 2000-2007 is 11/16.
