Thanks for the info guys. Cars at my dads place so haven't been able to work on it till this weekend. I think we've decided to replace the master cylinder with another one and if that doesn't work. I'll try what some of y'all have suggested.

The thing is it flows out smoothly, it just doesn't shoot out very far, nor did it pop at all. Also the brakes seem to release smoothly, which I've heard isn't typical of a kinked or blocked line.

Yeah, there is fluid coming out. We've gone through a whole bottle in an attempt to bleed it. It doesn't come out with much force at the rear right bleed, it just barely flows out.

No, only thing we did as far as the brake lines, was flare the old brake line because i broke it off at the wheel cylinder. The rubber hoses, while old, looked fine, except for 1 which was frayed a bit. Again no leakage though.

Working on my dad and I's 69. The cars been sitting for the last 30 years more or less, and hasn't moved at all up until this summer for at least 20 years. We cant get pressure to the brakes, the pedal goes all the way to floor. The front calipers will just start to grab at the very bottom, and if i pump the brakes i can build up enough to get the rear drums to grip. So far we've, replaced the brakes all the way around. wheel cylinders for the drums, and the master cylinder. We've tried bleeding the brakes multiple times, and the master cylinder itself. We haven't noticed any fluid leaking out of anywhere else. Its gotten better but is no where near safe to actually drive. My uncle helped us work on it today, who's really good with brakes was stumped. Basically we came to the conclusion that it may either be the proportioning valve, or we just got unlucky with a bad master cylinder. Anyone else ever encounter this problem?

Thanks for the input guys. I'll just rebuild the drums and save the complete restoration until after the body work is done.

Hi all. Me and my dad are in the process of restoring a 69 Mach 1. It's been sitting some time and since the brakes have gone bad. We pretty much are rebuilding the entire rear drums. Here's the dilemma, should we just drop and rebuild the entire axle and get it cleaned up. Or replace the brakes and deal with it later after the we send it off to get the body work done? The car needs to be in driving condition for the body shop to take it. I'm in favor of just dropping the entire rear end axle and suspension sending it off to get sand blasted and painted then just rebuild it and be done with it.
