Joe, I'm a little concerned about this. I think the pushrod from your brake pedal to the master cylinder is miss-adjusted. Brake shoes run out to tight would not usually result in a brake light switch becoming pressurized and actuating while sitting because the master cylinder relief port would normally bleed off any excess pressure built up in the line. However, if the pushrod from the pedal to master cylinder piston isn't adjusted to leave just a slight amount of free movement between rod and piston the relief port in the master cylinder is covered no longer allowing line pressure from heat to relieve into the reservoir. A broken brake pedal return spring can also cause the piston to not return to the rest position.

Just a friendly thought for your consideration.

Your car looks fabulous!
