Re: Found a Sweet Engine, What Now?
I have very little experience with bicycle hydraulic brakes, but I have heard of ''daisy chaining'' two calipers to one piston. I think it would work.
You might need to use a larger piston lever to actuate two calipers since you are effectively halving the application pressure by splitting between both wheels.
Mixing a big lever with small calipers should be workable if a stock setup does not work well.
If more is better, then too much is just enough.
If you can't afford it, build it yourself.
