i'm gonna die if i don't fix this

Do you have rear drums? Have you checked the rear wheel slave cylinders?

If you have 4 wheel disc, what your describing is absolutely a brake-pressure-equalization problem, which could be a leaking proportioning valve allowing air into the system. Or it could be from a bad caliper that is somehow allowing air into the system. If you've replaced the MC twice and that temporarily fixed the problem but it came back, then it's likely that something you did DURING the MC install process fixed the problem, NOT the actual MC itself. Like, I dunno, bleeding the brake system. Which would remove the air in the line.

Oh, and I kinda doubt that a bad brake booster would be in the world of possibilities for this. It's air in the line, the question is how.

That's what I thought. So I was thinking its either my prop valve or my caliper. But I'm losing fluid too now, so I'm guessing its my front right brake caliper. Anyone got a good used one for cheap?

after all this, your still trying to buy used/cheap brake parts...
