Rear disk conversions

[71meangreenc10]

All,

Looking for some advice, I have done two conversions and really not satisfied with either.

I am about to change the prop valve out on my truck to an adjustable one because I think the rear brakes are not where they should be. My question is, should the rear lines also be changed out to smaller diameter lines or will the adjustable prop valve take care of that?

Brakes have been bled to death, no air, no leaks. Have the Camaro kit on one truck and a CPP kit on the other. Everything is new on both systems from lines to calipers.

Thanks,

Smitty
