How are you guys plumbing your brakes? If you look at the Aerospace brakes instructions for plumbing dual rear calipers. It looks like they are saying to hook the front and rear ports together with a tee's. Are you guys doing it this way? I am sure it works but what happens if a line breaks. Seems like you would have no brakes instead of weak brakes.
