A buddy of mine lost his right leg a few years ago in a motorcycle accident. He still rides with an artificial leg and currently has an EVO era Softail. It takes him a few minutes to get on and off the bike but he does well.
Problem is he cannot use the rear brake and several of us are looking for a way to tie the front and rear brakes into one system controlled by the front brake handlebar lever. We believe that a larger fluid reservoir and an adjustable proportioning valve would be required.
Does any one have any knowledge or experience with this type of system and where parts could be purchased?
I had been thinking about this same thing for awhile too.. my neighbor down the street has a degenerative hip disorder.. his hip is disintegrating (for lack of a better word) and has to wear a special boot and stuff because his thighbone has slide upwards into his hip joint..so one leg is like 2" longer than the other, he rides a Dyna and doesn't have much issues getting on and off of it.. but i can imagine he's go problems with the rear brake.. and although he hasn't tried anything like this it got my mind rolling..
i don't see why it isn't possble really.. and unless i'm missing some sort of critical error, all you really need is a longer brake line for the rear, and a double banjo bolt..something like:
not sure you'd even need a bigger reservoir once the lines are full and everything is pressurized... the only thing i'd worry about is whether the level of pressure required to get the front brake to grip the rotor is different than what is required for the rear brake to grip the rotor.. because if one brake locks tighter than the other..you might get some fishtailing going on and cause an accident..
Bob - you would want the dual disc master cylinder like on a Touring bike. Believe it's around 11/16" bore. You can pick up an adjustable proportioning valve at a Hot Rod shop or similar.
Another option would be to move brake to the opposite side using a hydraulic clutch set-up and adding an electronic shifter.
Even another option would be adding the auto clutch.....
I must say, it's a great thing that your bud still wants to ride and even greater that he has friends willing to help him out in his quest! My hat is off to ya'll!!

+++10 On helping out your friend. I have also seen a heal controlled pedal for the rear brake on a custom for a handicapped rider... It was on a trip out West... I'm searching for some pics that I took.
