A brake booster works off engine vaccum to "assist" or "boost" the braking power. If the vacuum system leaks, it can/will let a LOT of unmetered air into the engine, causing a stall.

Remove the vacuum boost line on the intake manifold (follow it from the brake booster) and plug it with a rubber cap. If you can brake without the engine stalling, you've got an air leak somewhere in the power brake system.
WARNING, you will NOT have power brakes, take it easy, do this in a parking lot or somewhere SAFE.

:D

my buddy had a problem sorta like that last summer with his mustang. It turned out that a wire that went to the distributor was grounding itself out on the pedal. I'd check through all the electrical stuff in that area first.
