All Gas No Brakes - Stiff Hard Brake Pedal Porsche Cayenne

My Porsche Cayenne mysteriously woke up with a super stiff brake pedal and apparently no brakes. A little test drive shows that has a brake pedal that barely moves, needs to be STAMPED on to slow down even from a walking pace and felt like brakes were 95% broken.

Big panic on my side, imagining a huge Porsche repair bill but it turned out to be something super simple ;)
