VACUUM LEAK FROM BRAKES ON `89 90Q W/ABS

[David G]

Almost certainly the vacuum booster.
Boosters rarely fail, so I would use a used one on my car.

My car has lost the vacuum assist on the brakes.  When
you push the pedal in you can hear a hissing sound
from above the brake pedal, and the car starts to idle
funny from the leak.  Any suggestions?  Thanks in
advance.
