Brake pedal gets stiff when A/C is on?


I drive almost exclusively with no A/C, even in Louisiana heat and humidity. My windows are always down...

Yesterday, I did turn on the A/C, and noticed that my brake pedal got really stiff... almost like I didn't have power brakes. I know for a fact that the car has never done this before, and this all started suddenly.

Does anyone know what could be causing this?

My Mustang is slowly dying on me all of the sudden... transmission problems, electrical problems (well, I've been having those for a full 120,000 miles), etc.

Maybe you need a new Alt, or new battery.
