What proportional valve?

What did you use with your 14 bolt disk brake conversion?

I used the stock prop/combo valve. i am running a MC from a C3500 as well as the hydro-boost from the same truck. Stops on a dime and front and rears lock up at almost the same time...

Thats what I was wondering. I'm running a hydro brake system as it was on the diesel tub that I used.

I'm also just using the stock stuff on my '90 K5 with a 6.2 and hydroboost.......no problems at all.
