Linking the brakes????

(1/3) > >>

Hi all. Just thinking out loud but I'm struggling a bit with where how and how much! This is all to do with ditching the original rearsets on my cb750 sohc f2. Yozzers build has been an inspiration so now I want to do something a bit different as we all do with custom builds, but don't know if it will work well or even be safe, so I've been thinking about different ideas and this is the latest mad one.
Getting rid of the rear brake pedal and linking the rear caliper to the front lever with a splitter and braided lines. I do realise that bleeding it will be a bit of a nightmare.
Let the comments commence.

ka-ja:
I seem to remember this having been done on a bike some years ago, it involved a pressure reducing unit to the rear brake, but as I go senile, memory is a bit iffy!

    Look up "combined braking system" on Wiki. Also   http://powersports.honda.com/experience/articles/090111c08139be28.aspx

Woodside:
Don't some motoguzzi bikes have a dual braking set up..and others I would have thought. .

JamesH:
Technically possible, but imho would be a total pain in the arse to adjust your riding style to. Also, what will you do when attempting a hill start? Not exactly the best riding experience trying to adjust the revs, find the clutch bite point whilst holding the front break lever..seems like a recipe for disaster...

Chris400F:
I seem to remember that early incarnations of linked systems had one front disk and the rear linked, with the other front disk separate (but I may be wrong!).
Looking at ka-ja's link Honda are doing clever stuff with their system.
Crucially I think that there must be two braking circuits, in the case of a bike actuated by separate controls.
So I don't think you could have a braking system controlled by a single lever, unless you were going to go down the dual circuit route used in cars (sounds very complex).
