You have the right idea about the system.

Welcome to the board.....

I know the front brake lever puts pressure on the front brake and some on the rear...but from the diagram I don't see how??

Can anyone explain?

There's a secondary master cylinder on the left fork. When pressure is applied to the frt brake system, when the bike is moving, this caliper pivots creating pressure in this secondary master cylinder sending pressure to the rear braking system.
