It would be futile to get into a detailed discussion of F150 brake systems. I think we can both agree that losing the front brakes will cause a serious degradation of brake performance; in my opinion a much larger degradation than most would expect. The point I was trying to make is that unless properly engineered, dual brakes are not the panacea most would expect. Just throwing a dual chamber master in will not necessarily provide true dual braking performance. One could just as well end up with no brakes at all on one part of the system if the other part fails.
