Thanks for the links. I replied with points picked out of memory. My misses were using extra high grade lubrication and the returning break callipers.
Those rules needs to be upgraded with at least driving the car for a period of time/driven a minimum distance in normal traffic where you have to break hard at least once and then put it directly in the lab. My Mercedes Vito van would get seriously lower mpg if they had done that. Crappy breaking system, I'll have to put new discs and pads on all four wheels.
