Thanks OrrieG. Funny you should mention the proportioning valve. I just installed a new one, the original one was leaving a small puddle of brake fluid everywhere I parked - bad leak. That's what motivated me to post my original question. I suppose I was expecting the performance of the new valve to help the brakes lock up, but evidently the old original valve performed just fine as there's no difference in performance between the new and the original. No more leaks on driveways luckily with the new one.

I'm running 32" tires on stock 15"x8" ralleys. Slightly bigger than stock but probably not enough to make a differnce. I'll adjust the rear brakes some, but I think I'm ok with how the truck stops. It just kind of struck me as odd that the brakes never really locked up. I'll see how a rear brake adjustment helps.

Thanks!
