Sounds like the vacuum line to the booster from the intake manifold is compromised in some manner.

The issue will be compounded by the vacuum leak and the fact that higher engine RPM's produce less vacuum.

Problem Solved!

Thanks to the above replies. I found vacuum hose from booster to intake manifold dangling. Plugged it in and wala - idle & brakes back to normal.
