Yup, booster seems kaputt.
Drove it around the block - If light throttle is applied, brakes works just fine.
Pulled the vacuum line from the booster fitting - engine idling - nice suction, enough to make mark on the finger (best I can explain w/out gauge). No loss of fluid in the master cylinder, I dont think that is the culprit.
How hard is to replace the freaking thing?
