brake vacuum issue

[farmbs]

I have a 97. I'm losing power brakes after i pump the brakes once.. I have vacuum at the booster... How much vacumm?? The pump is sucking fairly good.
Wondering if the booster or the pump is a common problem... Like i say the pump has decent vacuum... Anyone got a number for inches of vacuum?

Thanks all

The one way valve at the booster good? Does the pedal feel go to the hard side or go to the floor?

Thanks for the reply.... The next day the pump started making noise.. then i kinda quits on and off... So definitely the pump.....
Thanks again!!!
