What does it mean, say when I push my brake pedal and my lights dim (head-lights, dash, ect..), or when I rev it up my light get brighter.?

My car does that too. New batt and alt also. I think it may be the volt regulator.

Sounds like a possible bad ground wire,a short or a toasted alternator, also , just for laughs test your battery.

Sounds like it is relying on the alternator too heavily.
1. Make sure all battery cable and solenoid connections are correct and tight on each end, and then connect a new heavy 10-12 gauge braided ground strap between the firewall and the bell housing.
2.Then make sure the engine idle speed is correct at idle on a straight shift, and in gear on a automatic. (750-850 rpms)
3. Then make sure the alternator belt is tightened properly.

Worked for me on my Pickup. Fixed hard cranking and dimming lights.

When you push your brake the brake lights come on taking amperage from your system. All of your system probably is fine it's just that it can't take that much total load. I have a new car that my headlights dim if I hold own the power window button.

Mine dim at low rpms too, I think its just the nature of the beast. I've been thinking about putting in relays to the headlights, there's some good internet how-to's on it.
