Default Major Brake Problem.

How do I know if I should change the Brake Booster or the Master Cylinder or something else? Here's my problems: rock hard brake pedal, car barely stops even when brakes are FULLY pushed, when ever I press the brake pedal my idle changes and my headlights/interior lights dim quite a bit.

NOTE: I changed my brake pads, rotors, and bled them and still nothing.

The only connection between brakes and idle speed is vacuum via the booster. Sounds like a bad booster to me.

Been there done that..... if it takes both feet to fully depress the brake pedal while driving, you're booster has went out or the vacuum line going to it has a leak or has come loose, although the latter would also make the engine run like crap because of the vac. leak it would create.
