Intermittent no pedal condition,No pedal. Brake. Failed, caliper dragging semi r

[Treo Benajan]

So one day I was doing something on the truck nothing to do with brakes really but I had pulled the caliper off and hung it up by a bungee cord well checking the width of the rotor, which is albeit very close to needing replaced within 1 mm. So I put it all back together and start to drive and within a hundred feet I realized I don’t have any brakes the pedals totally spongy.
So I investigate and find that the master cylinder is bad I replace it and within a week it’s bad again, I also see rubber and metal flake in the fluid, so I order all new rubber lines, my vehicle just hit 200,000 miles on a 2007 Honda Ridgeline, yay happy birthday to me so then I get no pedal for the first half and then and then pedal and that last for about a week and then it totally drops out to zero, leads me to believe that maybe it’s the intermittent failing of the booster. I ordered one. During the 10 days it took to arrive I was able to figure out that the Pistons aren’t serviced very well, so I bleed the system with over a gallon of fluid and it isn’t until I buy a vacuum pump that I release through one of the lines a lot of Milky fluid which I assume is water. I don’t have a replacement kit for the hardware but I rebuild the calipers is best if possible I bled the system tonight and had a no break situation I left one of the leader screws open and took a nap as it gravity bled it came back out a few hours later the fluid hadn’t increased in the bottle but there was a firm pedal, I don’t trust it of course because this is the third time that I have encountered over the last 10 days a firm pedal I’ve driven it sometimes I get up to a hundred miles away before it fails and I have to limp home on emergency brake. So I’m sure it’s some multiple situation condition the bleeder screws were all leaking of course and I had to rethread them tap now everything seems pretty much okay but I’m certain that the calipers in the front need to be replaced cuz they were pretty badly pitted, I did hone them today, we’ll see if I have another failure I’m not sure if I trusted of course. And because of censorship on the internet there’s even less information floating around about possible reasons for all of these things, I have the manual the pains one it’s not that helpful. It just tells you how to change the brakes not actually had a troubleshoot any of the issues that I’m having.
