I just got a Goodridge (DU2801 - 2FP) front brake line kit for my '95 M900 and I have no idea how to install this. My M900 have dual calipers on the front and the two brake lines hooks into a junction box (behind the headlight), the junction box is controlled by a cable into the master cylinder. I googled the Goodridge kit and it said "2-line race kits. Dual front lines run directly from the master cylinder to the calipers thus eliminating the junction block." so how do I run the two lines from the master cylinder???
You use a double banjo bolt on the master cylinder and then route the lines to each caliper (any way that they will work). You are replacing the entirety of the stock setup.
^^^ What he said. The lines coming out of your master cylinder should look something like this:

...and then you simply run one line to each of your calipers.
you would think they would have supplied said double banjo. galfer includes new banjos and crush washers. bummer
Do your self a favor and buy a double banjo bolt that has a bleed screw in the end of it if you do not already have a bleed screw on your master cylinder.
Pay close attention to the fittings to make sure there are no leaks of brake fluid when you are done.
good luck
