Technical Juice brake conversion Question.

I have a pair of 48 F1 self energizing brakes. I plan to use the on the front of my Av8. I also have an earlier pair of 47 non self energizing brakes I was going to put on the rear. [Actually was gonna use the whole rear end with a spring perch adapter.] My question is since the fronts do 70 percent of the work. Would this setup be satisfactory? properly adjusted of course.

 

i have a 40 ford with that combo i am using the orignal master cyl been on the car 25 years stops on a dime

 

My '40 Tudor has F1's on front and '40 on rear. Much better than stock.
