Thanks to Charlie Mullendore of Antietam Classic Cycle for posting this on the old Yahoo! Loopframe_Guzzi news group (which has now moved to Groups.io). In Charlie's own words:

Tom Christian's experience

Tom Christian replaced his stock hydraulic brake lines with stainless steel, black coated Goodridge lines. By doing so, he improved the braking feel and performance while maintaining the stock appearance. Here is the information from Tom:

A couple of weeks ago I installed stainless steel black coated Goodridge brake lines on my disk Eldo and rebuilt my stock 15 mm master cylinder. The improvement is significant, and the appearance remains period correct. The install was trivial, takes at most 12 hour, with bleeding.

Here is the part ordering info:

I'd take at least an inch off of each hose, and go with all 4 banjos at 45° if I had to do it again. The screw-on connectors need to be tight!

Gordon threw in the brass crush washers but I forgot to order new stainless steel banjo bolts - Goodridge's are nice, I've used the stainless steel on our Harley too. The old banjo bolts will work fine, however.

The whole thing was about USD $100.00. Takes less than 12 hour to install and bleed. Some of the parts come from different locations, so shipping was slower than usual (I usually order Monday and it arrives Thursday like clockwork for the weekend) - this added a couple of days.

When I said new master cylinder, I meant I used MG Cycle's rebuild kit and rebuilt my stock 15 mm master cylinder - it was a mess.
