I was stuck in a german manufactured truck in the Army, that I was not signed off on
(it was stationary). Unfortunately the previous user had not put the hand brake on and it started to roll back. I was puling anything with a T shape or an angled lever, all the while putting my full weight on the conventional brake pedals (no manifold pressure). Someone else had to climb in the passenger side and pull the actual hand-brake. It was a SQUARE! wire handle painted YELLOW! I'm ex airforce, so square wire handles is a cut-away shape for parachutes, and yellow is a danger colour for something that can't be undone when pulled (I thought it would cut away the box body from the chassis or something). I have a lot to say about Kraut engineering these days, not a lot of it complimentary!
