That's true Dieter, and here's another couple of things to consider. A larger MC bore will also take less travel on the brake pedal to apply or lock up the brakes, and by the same token, a larger wheel brake cylinder will require more travel of the brake pedal to get the same braking effect. The larger MC bore pushes more fluid than the stock bore at the same travel, and the larger wheel brake cylinder will require more fluid to move it the same distance as the stock bore. Confused yet.
