I recently had to replace all 4 rotors, pads and both rear calipers on my '06 H3, and after bleeding the breaks i have completely lost break pressure. As i was looking at the MC i noticed that fluid was coming out of the ports for the rears but imgetting noting out of the master cylinder for the fronts. Problem is a new MC is crazy expensive so i was hoping to find one off of another vehicle from a pick and pull but cant seem to figure out what other vehicles besides hummer have the same master cylinder. I also found a repair kit but it doesnt seem to have an o ring and a couple other things i would think id need to rebuild it... Before i drop 450 bucks on a new MC anyone have any ideas that would be AWESOME!!!!!!

 

Take a look at some of these...
