I have a booster if you need one. It has a shortened rod tip, and a Chevy C10 master cylinder bolted onto it, but it can be swapped back to fit your stock parts.
Or you can use the chevy MC if you want.
Anyway, you can have it if you drive to Laurel to pick it up. It was new (reman) a few years ago.

I have to have another master cylinder because mine has a blown seal because if a pump it really fast it’ll get hard for a second then go down really fast

I concur, Doctor. (TV show joke, I think from M.A.S.H.)

I agree with the above, sounds like a bad master to me. Especially if your fluid level isn't going down. Typically a bad booster will cause the opposite and the pedal will get really stiff. If there's a big enough hole in the diaphragm you can sometimes hear it hissing for a few seconds if you press the brake right after shutting the engine off. If you are stupid like me and forget to bench bleed the new master you can crack the flare nuts loose on the master cylinder and have a buddy pump the brakes to get any air out that may be trapped in there. You'll probably want to put a rag down since brake fluid eats paint. You'll also need to bleed the brakes out again afterwards.

My car has a slow master cylinder leak. I top it off every few months. I will fix it once it starts dripping or the brake pedal starts to lose pressure. First noticed it a year and a half ago lol.

when we pump the breaks all the way to the floor it makes a moaning sound and the fluid in the master cylinder goes down just a tad so there has to be a leak somewere and i have no idea were but i think its somewere up front. i need an idea of were common break leaks occur on a hardbody if that was a big issue for these things but i dont think it was.

I'm at 256k miles, and I've never had any brake leaks.

So, I don't think leaks are an issue, but like all things, shit breaks.

Wheel cylinders always seem to leak first. I actually had one fail quite spectacularly to where it sprayed brake fluid all over the inside of the drum and I lost all pressure in the pedal. After that I replaced both the calipers and all the lines pre emptively.

replace both wheel cylinders when you do this or the old one will explode on the first drive.

I had already replaced both when I did the brakes the first time. It was a cheap shitty reman one that failed. Both have since been replaced.

Luckily I was just pulling into the parking lot at work when it happened.
