Yeah it stops perfectly fine which is why I figured it was just a "Porsche" thing
Only problem comes when someone in the household moves from one of the other cars to it and have to re-learn braking by pressure rather than travel.
But yeah. It "feels" like a car with a non-working brake booster except it still brakes perfectly fine and it doesn't require (much) more pressure than any of the other cars here.
I guess it's time for me to go hunting and see what I can sus out.
At least now I know that it's not actually "correct"
