Generally The brake light only indicates the parking brake is on and/or low fluid in level. You are correct that it indicates a vacuum leak recheck ALL vacuum lines you should be able to hear it as well.

No the light and chime does not indicate worn out brake pads or shoes.
However, you were correct to add fluid to the correct level.
Just to be clear, you are talking about the red brake indicator light on the dash and is not accompanied by the amber ABS brake light.
If the ABS light is not involved, there is a magnetic switch located in the brake master cylinder. When the fluid level is low, it triggers a switch in the master cylinder and causes the light to come on.
Some times a "gentle" tap on the master cylinder reservoir will loosen the stuck float and turn the light off. One way to verify the switch is causing the issue, you can disconnect the harness connector at the master cylinder and the light should go out.
Start there and let me know.

check to see if all the bleaders are closed on the calipers. make sure all the lines are good also. something could have shacken loose.

Sometimes the float in the master cylinder gets stuck and you have to carefully work it up and down with a screwdriver or something. The switch might be bad on the float too. If the low fluid switch is telling the system that the master cylinder is low, that will cause the "Brake" light on the dash, to come on too.
