i don't know, are power brakes and dual masters really that safer? i have seen way more accidents caused by aftermarket parts or parts not originally for the specific application, but i'm no expert. i think drum brakes last longer than disc, they usually run cooler too. i mean if you are going to be tailgating someone, or if you just want them, by all means, go with disc brakes. if the flex lines, master, wheel cyls, and hard line are all good why upgrade?
