ok, so pretty basic question here. does the red brake indicator in my dash on my '83 k5 indicate that my e-brake is engaged or that one of my brake systems is failed? i ask b/c randomly over the last couple days, it will come on while driving and then go out after a short period of time. my e-brake isn't hooked up and the pedal isn't depressed, so i don't know what would trigger an e-brake signal. both my braking systems seem to be working fine. fwiw, my wiring needs help bad - so maybe just a shorting connection? what do you think?
