Brake light stays on

If the red light always comes on and stays on for a
few minutes right after you start the car, then goes out,
you may have a slow leak in the brake master cylinder servo.

To verify, remove the hose exiting from the brake master cylinder
into the oil reservior (where you add Pentosin) after the car has been
running for a few minutes, then look if there is a very slow drip out
from it....this is what bleeds the accumulator down after it has
been parked fior a while,
