Jeremy,
Good question. I do have the 57's with dual filaments lol. The brake lights went out before I changed anything out and it was both of them, yet the hazards still worked.
Great news though!
So I had an avionics friend who was real familiar with electronics come over. There were 2 contributing factors potentially. The previous owner had cut and spliced the LG/R coming into the brake switch. With a crimp connector. Which was cut from somewhere else, and had both LG/R wires stuffed into one side. Wiggling it would break the contact. That has now been replaced by an appropriate crimp connector with good contact.
The real issue turned out to be the wiring HARNESS on the multi-function switch. We traced the voltage all the way up there, took the steering column trim off, and found that the light green wire (leaving the brake switch) had broken off the retaining clip on the wiring harness. We applied some tape, tested, applied some superglue, and stuffed it back in there. Picture below:
PICTURE!
With the wiring harness at the multi-function switch fixed, I now have brake lights again!
P.S. I was using the multimeter totally wrong, and my buddy corrected me on that. There was power across the brake switch.
