Brake Petal Whine

I've noticed recently, that after a complete stop the brakes make a high pitch whine while I switch from brake to clutch. The noise relates directly to the up travel of the petal. Is this a sign that my master cylinder is going out? Booster? I checked the reservoirs and the fluid is a little yellow, but its still full. Ideas?

Sounds like a bad booster. Squeeze the large vacuum line going into the booster with something to clamp it off & attempt to repeat the same scenario again. If there isn't any noise with the vacuum line clamped off, it's a bad booster.

There is no situation that cannot be improved with a small but well-placed explosive.
