very wrong indeed.

The anti ice bleed valve is selectable in exactly the same way as the HP bleed valve
wrong again, the HP anti surge valves are NOT pilot selectable, the anti ice air take off is. and is available continuously for selection.

and emergency brakes.
what emergency brakes ?
the brakes are electrically actuated and can be operated by battery power alone, i'm not aware of any emergency brakes being fitted to the aircraft.
but then i'm in a minority of one
Here, you are confusing the surge bleed control valves (which are controlled automatically and scheduled by the ECS) and a HP valve which is selected by cockpit switches. The 787s do NOT have HP VALVES.
Emergency brakes POWER is from the battery. Jeesus what a pedant!
