Brake pedal can be pushed nearly completely down to the floor when standing
also when doing this, it sounds a bit like when the steering wheel is turned to the end stop.
the brakes work normally all the time, also when driving very slowly or at higher speed.
is this normal?

if your not aware, your brakes are a hydroboost system which is run off your powersteering pump.

My rigs been torn apart for 8 months under a massive rebuild otherwise I'd go out and confirm that for you.
