Brakes went out on my 69 firebird, soft pedal. Relaced master cylinder, no change. Boster seems ok. I'm working out of town all week, so the kid tried bleeding the brakes. Snapped off the two front bleeders, kids. Anyway whats the best way to replace bleeders and what the heck made the brakes go away? It's front disk by the way. Here I though I'd come home and relax, not. Thanks Ted
