So what do you have for voltage at the battery?
Sounds like the alternator went bad. There should be around 14 volts at the battery with the engine running. Anything less and the alternator would be the first thing I suspected.
Check to see if the belt [ s] are still on the motor. You may have had something seize and break the belt that powers these items. There is also a seperate belt that powers the A/C [ lower right side of engine ].
disconnect all the connections to the battery and clean them , also clean all the grounds, check the alternator to engine ground, and engine to body grounds, what you describe is indication of a bad connection and applying the brake is enough to to lower the voltage needed to power the ignition circuit, brake light use a lot of juice
I have a 2003 Ford ZX2, and I think I had the same problem before, I think it is a fuse somewhere. I believe that the breaklights and dash lights are connected. My dad is a mechanic and I will check with him.
