Since I need a new master on my 4100, a dual setup would be the way to go depending on how hard is to do??? It would be great to have the option of an adjustable proportioning valve for
front/rear brake balance, along with having at least 1/2 brakes if something goes wrong. One big leak anywhere on a single master, and you are in big trouble.
