I have got braided lines but following the standard pattern, ie one from the master cylinder to the junction block and down to the wheel cylinders from there
Thanks Pete,
Whilst air was a problem I did get there eventually... excessive lever travel is the real problem.
I ended up making up a 2.5mm by 13mm dia plastic spacer disc to insert between the end of the master cylinder piston and the seal mounted on the spring.
The effect this had was to push the seal closer to (but not over) the relief hole in the reservoir when the lever is at rest. This in turn means that less lever movement is wasted before the the hole is covered so fluid pressure can build and brakes start to engage. The big fluid fountain coming from the hole is now just a little squirt.
The end of the lever previously traveled about 40mm toward the throttle before fluid pressure was able to start building up. now it takes only 10mm of travel to get to the same point. The lever is now well clear of the throttle grip under max braking rather than hard against it. Two finger braking is now possible.
Yay...
Political correctness: a doctrine which holds forth the proposition that it is entirely possible to pick up a turd from the clean end.
