Have a 2007 Lt2 z71extended cab. Done pretty good and don't know about that.Had all the problems brakes could have and then some. Today replace master cylinder. Was leaking fluid. Look all over for fluid. Leaking into booster. Hope it might help somebody. Got more good stories one of these days. Have 166,000 on truck. A truck not to keep for many years. Just my luck

Welcome to the forums Jerry, sorry to hear about your problems with your truck. Can't say I've ever saw a master cylinder problem on these trucks. I recommend also replacing your booster if brake fluid got into it.

Replace booster. Solve my problem on that part. Thanks again
