i ran in to the same problem today i had to put in brake fluid like 3 time and i just bought the master from autozone a while ago with lifetime warranty and today i went to check on it and the guy asked what kind of brake system i had and they didnt ask that before and he said i mite have the wrong one u guys think thats true? and what kind of brake systems do hoes have?

Not a great one. But definitely room for available improvement. That sounds fishy to me But he could be ASSUMING that he thinks you you have a hydra boost setup. We Stock a 4-wheel brake system with disc in front, drums in back 10" for 2dr, 11" for 4dr with a Kesley-Hayes 4-wheel 3-sensor ABS system and a vacuum booster.

the guy was saying something like hb-7 or hB-8 it sounded kinda crazy to me

I would try it and if it doesn't work then they do returns and u can try the other one

It has the booster, hydraulic lines and fittings. It ties to the power steering system.

It just uses hydraulic pressure instead of vacuum power.
