Hello,

I am upgrading to a Dual MC. I have the brackets and all. My question pertains to the brake lines used for the modification.

The tech-tip calls for 1/4" tubing going to the front end. I describes routing a 1/4" tube from the MC to a three way (recovered from the old system), and two other 1/4" lines going to each front wheel. Ok, but, the three way accepts only ONE 1/4" flaring nut, and TWO 3/8". So, how do I get by this? Are there flaring nuts that fit into the 3/8" port on the three way, but accept a 1/4" tube?

Similar are the tubes to the rear. The 1/4" should go to a 1/4" union, with a 3/8" tube coming off of that to the rear brakes.

As I am in Italy, and sourcing these is proving VERY difficult, I may have to order then from the UK.

Any insight to this? Are 1/4" necessary to the front? Or can I take a 1/4" to the three way, and 3/8" off that to the front brakes?
