I have never done this before so gave it a try.
Pressed the brake pedal and it went down about 30mm and hissed. Pumped it 3 more times, each time travelling slightly less but hissing then it went solid.
Keep pressing start engine and the pedal goes down about half way.
Stop engine and wait 2 minutes...pedal goes down about 10mm to take up slack but then rock hard.
I would say mine is the same as yours.
