Easy....
find about $150 and get yourself a new (reman) booster. Around $350 with new master cyl attached.

Mine just failed too. Pedal is INCREDIBLY hard and darn near takes both feet to get a good stop:ugh...an emergency stop is probably not possible, it's so hard.

Looking at the size of that booster you can see how many sq inches x PSI are available to help your foot...I had completely taken the "power" part of power brakes for granted..:eyerole

Of course, check all your vac lines and make certain that its not just a vac leak. If you must drive it, d/c the vac hose to the booster and plug it so the leak is not screwing up the vac in the intake...it does. Makes the engine run bad and do weird things.

THAT SOUNDS LIKE EXACTALY WHAT MY PROBLEM IS BUT WOULDENT MY BOOSTER BE WEASING OR I WOULD HEAR SOME SORT OF LEAK RIGHT? BECAUSE I DONT HEAR ANY KIND OF AUDABLE NOISE FROM IT AT ALL :confused I KNOW MY MASTER CYLINDER HAD A LOT OF GUNK AT THE BOTTOM OF THE CUPS AND THE FLUID WAS RELLY DARK ANY WAY IT COULD BE THAT THE M/C IS FROZE UP?

Crack open a bleeder screw and see if fluid squirts out when you step on the brake pedal. If it does, bad booster. They don't have to make noise when they blow.
