Re: D30 disc set up on the rear?
Not sure how big of tires you are running, but with stock brakes and 33x12.5 tires I can easily lock up all four on pavement after adding in a better brake booster. And that's without making like I'm doing a leg press of 500lbs. Prior to that, I could barely make em squeal with ridiculour full leg effort. I used a Chevy S10 dual diaphragm booster and that did the trick. There's been a few guys convert to rear discs and gain little or nothing but headaches. I believe the stock system doesn't generate enough braking pressure. If the problem was brake fade because you were racing, mountain driving or towing, then I'd say you need more brakes, but without those problems, you might want to consider swapping to a more powerfull brake booster instead. Unless of course there is some other reason, like water crossings affecting your drums.
