I've noticed that when i hit the brakes, my fuel pressure rises, which obviously means a drop in vaccuum. If i hit the brakes fast and hard, it's like pushing a brick wall, the pedal goes nowhere. If i just push with normal pressure, they act normal. Does this sound like something vaccuum related within the master cylinder or booster, or do I just have a normal vaccuum leak? Thanks

Eric

So, you think you may have a vaccuum leak in the booster?
Plug up the line to the booster & see if she smooths out. I actually did have one with a leak once.

how do you RPM's act while doing this?

The hose that goes to the booster can leak around its rubber gromet. Flex the hose around where it connects to the booster and listen for a hiss.


With that said, I really have no clue
