I will take it to local mechanic Tuesday morning but thought I would share the issue with you experts since I am new to the board after not owning an Oldsmobile for many years. I owned a bunch of them starting with 1977 Olds Omega Brougham (my first new car) and even a 1983 Regency Brougham before they quit making rear wheel drive models. When brake pedal is squishy, you feel it try to stop part way down and then pedal breaks loose to go further down and at same time you hear a "whoosh" sound Presumably vacuum but not sure since I am not a mechanic.

Thank you fellow Olds lovers.
