If I understand linked brakes, (as in the case with Honda Silverwings), there should be 2 brake hoses attached to the front caliper.
One would go to the front master cylinder (MC) and the other would go to the rear MC.
Thus the front brake could be actuated by either (or both) MCs, but due to the number of caliper pistons involved, the applied action might not be equal for both MCs.
My GV (2009) has only 1 hose to the front caliper, so it does not have linked brakes.
I would like linked brakes if it were well engineered, but happy enough with the present system.
