Who's fought Silverado/ Sierra brake problems? and won?

Del, if you really hate the way these feel maybe you can find a larger bore MC that will move more fluid.

I think they are probably just fine. Its just the way GM truck brakes feel. I have bitched every time I drive one....and being in the car biz I have driven ALOT of them. I sold GMCs for 3 years in the 90s....
