What's the fluid capacity of your new vs old? Smaller master dia bore= more psi= better brakes provided you can move enough fluid to push the pistons as far as they need to go. How much vacuum do you draw at idle? Not positive how a booster works exactly but you had 4 or 5(ratio) x 60 sq in (minus bore) x your vac psi with the 8.75" booster vs 7(ratio) x 38.5 sq in (minus bore) x your vac psi now if that makes any sense to you.

Anything more than a 2 psi check valve is a bandaid anyway. My Durango mastered TJ has kung foo brakes without them.
