Has anyone used . . . .

their front brake lever to also work the rear brake? ? ? I see on some drag race cars, they use a proportioning valve, to adjust the pressure for the rear brake as opposed to the front, to compensate for the tire size . . . The reason wanting to do this, is, I don't have proper use of my right foot anymore, so pivoting my foot at the ankle isn't an option . . .

Mick Doohan the five time World GP champion also couldnt pivot his right ankle. he had a rear brake lever added below hiis clutch lever.

There are bikes with linked braking systems. I know the Goldwings have it for sure but they are kinda complicated with ABS. Maybe the Burgmans have linked brakes too. I don't recall if they had foot controls or not. If you got the hand control, proportioning valve, and a bunch of braided brake line you could make a system that's transferrable from your current bike to whatever you own next.

would you have to adjust to compensate moving more brake fluid from the master cylinder?

Check out this webpage and it's forum. They have a dual caliper carrier for the GSXR so that you have one caliper for the brake pedal and a second caliper hooked up to the front brake system. Maybe some of the people on the forum can give you some details on how well this works.

There are several left-thumb-operated rear brake master cylinders available for the racerboys. Judging from the prices, they are hand-carved from blocks of pure platinum by union elves:

I wonder if there's some way you could hook up your stock master cylinder with a modified lever arrangement so it could be thumb-operated.

Depending on the specific range of motion left in your right ankle, maybe you could set up the lever to be operated by your heel instead of your toe, or somehow modify the motion required so that it's more comfortable.

You could relocate the brake to the left side and operate it with your left heel (still shifting with your left toe), but that would make it pretty difficult to come to a smooth stop, unless you just do all your downshifting after you stop.

The law requires two independent braking systems, so combining the rear brakes with the front in one hydraulic system would probably be a Bad Idea.

Law will vary from state to state - CT does not require that. Best to check locally before you do too much planning.

Brakes
Each motorcycle and motorcycle with sidecar shall be provided with at least one brake. Motorcycles designated as 1974 or later models shall be equipped with brakes on the front and rear wheels, excluding wheel(s) of a sidecar.

Moto Guzzi's are famous for thier linked braking system, try looking up Guzzi forums on the web and ask some questions.

Talked with my dad last night about his Guzzi. The foot brake activates the left front caliper and the rear brake I believe he said it was a 60/40 split. The hand brake activates the right front caliper.
