RamTest... you need to just stop man... You clearly don't know what you're talking about. I just had this exact scenario happen and there's no way all 4 wheels will lock with the defective brake booster even with my 6'3" 190lb frame mashing the pedal. Try for yourself in a safe area. You'll see..
...Right up to when he said ""I'm putting ALL MY WEIGHT on that brake pedal trying to get SOMETHING to happen"" (emphasis by OP)
Press harder any brake pedal, with or without a defective booster, and all 4 wheels will lock, until unlocked by abs.
