Brake Plumbing Question

[GBJ]

I just put a Moser 9" with 95-01 Ford Explorer disc brakes (easy setup). So now I have factory front power disc and the rear as described, I need to change out stock proportioning valve. My question is I see and read all types of configurations. From vacuum booster/MC/PV, MC/PV with rear adjustment valve to just a MC.

At a local car show yesterday I saw this on all types of cars and trucks. A friend has a 77 Z28 pushing 600HP with 4 wheel disc and Wildwood MC only, stops on a time.

I have back problems so I need an easy pedal, talked with a Wilwood tech guy Friday who says he needs a walker due to back problems and his 73 Camara has MC only.

On my 72 C10 I'm coming up with a pedal ratio of 5.4:1, when googling what a stock 72 should be I get 6.1:1 to 6.33:1. I want to clean up the engine bay and get rid of that big bracket/booster etc.

What do you guy's have and what are your thoughts on all the combinations I mentioned?

Thanks, George
