That is a conversion drawing. The original brake line inside a covered landing gear V was a copper tube, the end of which is shown just below the axle with a 90* fitting. The new connector tube is that S shaped one on the bottom. IF the new connector tube went from that 90* fitting to the top of the brake you would have a loop which could trap another air bubble. This would become an even greater pain in the....
This design can be bled by first pressure feeding from the bleed valve up to the original master cylinder until full. Replace the master filler cap. Remove pressure pot, replace with clear hose to a can of fluid. Push brake pedal, turn on (close) parking brake valve, then release brake pedal, remove filler cap, top off master cylinder and replace filler cap. Open parking brake valve. Apply pressure to brake pedal while watching air bubbles at wheel brake. Apply parking brake. Release brake pedal, refill master etc. Repeat until there are no more air bubbles.
Not enough pedal after all air bubbles are gone? Apply brake, set parking brake, top off master, replace cap. Release park brake. Don't over do this as your brakes can become locked.
