FWIW, the water pump belt flopping that much, just a couple inches away from the pulley, needs to be addressed...

On your brake problem how old are your lines? Did the fluid in the reservoir go down after the hard stomp? Let it sit overnight and then stomp it and see if it goes down. Just give it the one hard stomp and not a pump. If there is air in there you don't want to foam it and make it look like more fluid. Did you bench bleed the new master before you put it in?
After letting it sit since the initial having to pump to get a firm peddle does it ever go back to normal peddle feel from just sitting?
That sounds like a ghost, or a sci-fi soundtrack from the 50's, featuring your typical theramin or ondes martenot instrument.

The Delco Alternator rear bearing is a common one because the rear bearing seal is exposed to severe elements and often wiped down and there by pushing dirt and dust into the bearing. Same sort of thing with idler bearings - water and dirt, especially from washing engines pushes into the bearings.

If you are daring and like to poke at your engine whilst it is running you can use one of these to find what one is squeaking if you can't pinpoint it with just your ears. (Mechanic's Stethoscope) Some people use a long screwdriver and hold their ear to the handle end.

Another trick is to squirt water at the suspected parts. Once the water hits, the squeal will go away. The safest way is to remove the belt and if the noise goes away it is something the belt turns. The idler bearings are the most likely suspect followed by the alternator and then the water pump. Rare but the A/C can be the source too. If the noise goes away when the compressor is running the bearing is bad on the compressor.
