    Old brake fluid absorbs water and messes with the system. If you know how to bleed brakes, the procedure is relatively simple. But, any place at all will do it for relatively cheap.

    My first guess is the master cylinder or the power pump that actuates it either had a rare hiccup or is about to fail. But IIRC you already had some morons replace it

    So I had new pads, rotors, and calipers installed by a reputable mechanic. I'm towing a boat so I wanted to to be 100% right. They also replaced some flex lines right in the wheel well so I know they had to bleed the system.

    I have blead a clutch before and the procedure for brakes seems to be about the same.

    It's the strangest thing though, it leaked one day, all at once, enough to give me a 95% unresponsive pedal. So I took it home and topped up the fluid and had my wife pump the brakes so it would theoretically start leaking again once it was under pressure. She pumped away for 15 minutes and nothing so naturally I assume she was doing it wrong. I got in and pumped for another 15 and still no leaks, but now I had a nice firm pedal. So I took it for a drive and the brakes worked fine. That was a week ago and I have put a few hundred miles on it and still no leak.

    At this point i'm afraid to take it back to the mechanic because it could be 1 of 100 different things since I can't find the leak. I will say, the master, slave and booster all are clean and dry and look fine from a visual inspection.

    You won't see a leak from a failed master cylinder. Like a Karate Man, they bleed on the inside.

    Sounds like maybe the fluid got too low, or somehow got air in the system and it caused a hiccup. You have a firm pedal now so I wouldn't stress too much. Brakes are pretty fail safe and rarely fail catastrophically. But just in case, be prepared to use the emergency brake...gently, don't slam on it unless yo have to.

    No brakes is a game changer...like no steering. But that's another story.

    Good to know about the master. Fortunately the front and rear brakes are isolated so when I lost the fronts, the rear drums still worked so I could limp home. It was an interesting ride, trying to stop 6k pounds of van on 30 y/o drum brakes.
