Hi... I have a 1990 XJ, I have Ford Explorer rear disc brake conversion on my Currie nine inch Ford rear axle. My front brakes, master, propotioning valve, and single diaphragm booster are stock. I have 33x12.5 x15 tires. I want good braking!
Anyway the stock booster is leaking vacuum per my hand vacuum pump test, so time to replace it. That leads me to perhaps replacing the master while I am at it, and perhaps the proportioning valve too.
What upgrades are suggested if any?
Different bore master? Different booster? What about the proportioning valve?
I see Quadratech offers an upgraded booster and master kit for "rear disc brake conversions" , see link below...

What of this kit? I see they say it has a 1.125 inch master, what is stock diameter?
What proportioning valve should be ran? one from an explorer or?
I am still new too this and appreciate your insights.
Thank You!
