Hi, new guy here... Blew a rear brake line on my 98 Z-71... Extended cab, short bed, 5.7... Looks like I can buy new prebent stainless lines for about $130... ABS hasn't worked in a while, but hasn't given me any trouble either, so I hope to not mess with that, and open any other probs... Truck has around 400K on it, with normal brake (rubber) line changes, etc... Anything else I need to be on the lookout for? Brakes are not new, but entirely serviceable. Just went through them a bit ago. Truck had the usual soft pedal, but it would stop with no probs. Should I put a new master cylinder(think it's been changed once already) on it? I've read something about an upgraded MC that is supposed to improve pedal. I plow a couple houses in the neighborhood so a faster pedal would be kinda nice... Thanks for your help! Den
