muddy WATER in my brake lines?

lost power to the brakes today, and came to find out this....

most recent issue since i changed the front disc brake pads last month along with spongey pedal to the floor.

Master cyl is shot.

Did you bleed the calipers out or push all the fluid in them back into the MC when you changed the pads? That also looks like a lot of moisture in the fluid

Is that the automotive equivalent of having "Prince Albert in a can?"

i used a C clamp to push the caliper piston in so I could fit both pads and reinstall. Do chevys require the brakes to be bled for just putting in new pads?? i've changed pads on 4th gen firebirds and my (ex) '76 sedan deville and they never gave me this problem.

Well brake lines will rust from the inside out. Brake fluid is ... I think hydroscopic is the term for it? Anyhow, it attracts water. Anytime the MC cap is opened, condensation is introduced. That combined with brake fluid change intervals that are often over looked can yield your results. Brake fluid also has a six month shelf life after being opened due to moisture exposure, but I digress.

If you ever get a chance watch it on YouTube where they do a cup test on brake fluid. They taker one cup of brake fluid and one cup of water in like take-out cups and flip them on top of each other. One leeches into the other and it's not long before u can't tell them apart, but you know the contamination is there.
