Default Linked Brakes

I have no use of my right leg and want to figure a way to use the rear brake on my 2008 FatBob. I am considering linking the front and rear via a proportioning valve. The bike is set up with 2 - 4 piston calipers in the front, a single 2 piston caliper in the rear and the front Master Cylinder is a 11/16 inch bore.

Here is my question – will the current Master Cylinder handle the 3 calipers without being “spongy”?`

Yes, it can be done. Have ABS?

Many of the touring bikes since (I believe 2014) have had linked brakes. I had them on my 2015 Streetglide, and liked them a lot, but they only worked at speeds above (I believe were 25 mph) so one would still have the rear brake only for use in making low speed maneuvers. So there may be a way to add them to your Dyna. Unfortunately, I don't know the answer to that one.

Maybe use an adjustable proportioning valve between front and rear

I would imagine you will need a larger bore master cylinder….maybe from the very same setup Harley used.
