I have digitails front and back on my 68 and they both stop flashing when the brakes are applied. I think it is how the cars are wired. Probably something to do with the brake switch signal overrides the flasher.
As for your turn signal led, I had a similiar issue with mine and ended up grounding those LEDs (green turn ones in dash) on their own ground (not tied into any of the other dash wiring).
