Linked brake line replacement?

[monkeyodeath]

My '79 1000SP brakes were de-linked by the previous owner, but the MCs weren't changed.

However, the PO did ditch the brake line that connects the rear proportioning valve to the front disk.

Is it possible to get a line like this made? Mark at Moto Guzzi Classics can get me a proportioning valve but the original plumbing is much harder to find.

Would be cool to get to ride this bike with linked brakes -- I've never tried them before and I'd like to do so.

I think this is what you want.

Be sure to check the parts diagrams for other pieces you will need:

I've bought lines that are extra long, but with the correct fittings, at NAPA. Then bent, shortened and reflared them.

I got a Spiegler stainless steel brake line kit from Harpers. (went with black rubber coating) , Factory fit, easy install.

Very cool, thanks for pointing this out! Mark made it sound like the brake line was both unobtanium and had weird fittings.

Does anyone happen to have a picture of how it's supposed to be mounted to the frame? Wondering if I need to also source the frame mounted unions between the flexible and hard lines.

It only mounts to the frame in one place - up near the front via a wire retainer with grommet. There are several places along it's length where Guzzi used short pieces of split rubber hose to keep it from rubbing on the frame.
