Question; why do we all run around on vacuum brakes instead of hydraulic? Every vehicle now has power steering so hyd power is already built in. I get why we used to use a vacuum system 50 yes ago. But a good hyd brake has sooo much more stopping power. The big rigs have run them for years. And with more and more (hopefully) diesel engines on the road it would be a good time to develop a good hyd brake system for lighter vehicles.
