All of my other lights are working. Running lights, turn signals, head/tail lights…. But not brake lights.

Could the switch that has the plunger to the brake pedal have gone bad? Grounding? If grounding, how can I check with a multimeter? Thoughts?

I doubt ground is your issue as the lights are all working otherwise.
yes check power to the brake switch, in and out when depressed.
IIRCC the brake power then goes thru the turn signal wiring/switch so it will only light 1 bulb when making a turn

Do turn signals work? I chased turn signals not working for over a year. Pulled, cleaned & checked every relay and replaced the turn signal switch in frustration only to find out the signal wires in the rear harness that plugs in along the passenger side frame were cut. Looked like they were cut by a razorblade, which made it hard to find. Hopefully it is the brake light switch! I have a perfectly good turn signal switch laying in my shop if you need one though :)
