Not sure how to proceed,I have checked and replaced the break booster, master cylinder, and abs pump and module.intial issue was a hard break pedal, after checking the booster, I found a broken Port on the passenger side of the upper intake. I replaced the intake, and checked vacuum, which was at 30 hg.replaced the booster check valve and booster which was full of break fluid. Replaced the master cylinder, which was leaking into the break booster.i also changed the abs pump and module with a good used unit. I bled the system multiple times, but I still have a pedal that is rock hard. I'm not sure what else to check everything else seems to check out. Also bench bled the master cylinder. Please advise what else should I check.
