Re: Power Brakes...
Sounds like your vacuum booster has a leak as you shouldn't notice a difference in idle unless you have a vacuum leak. Also, if you've changed out to a disc/drum setup, I believe the prop valve is different in a drum/drum versus disc/drum setup. Did you install a new vac booster or old setup from another truck? I've gone through 2 old boosters on my GMC since the power brake swap, and believe me, power brakes with a blown booster diaphram is harder to stop than manual brakes. It doesn't matter if you swapped the power brake setup from a small block to big block. Good luck!
