Re: Upgrade?
With the one ton and disks I'm betting you are at the limits on the stock master. Hydro boost will give you the strongest pressure possible out of any brake system that came on a Chevy truck. I've heard a lot of people say once they upgraded to the bigger brakes hb helped a lot with the extra pressure needed to push the calipers. I have disk all around and still use the stock system. I just gutted the prop valve and took out the rear residual valve so front and back get full pressure.
