I noticed that when I release e-brake handle right after I started the car e-brake light stays on for 1-2 min and then goes off. But if I warm up the car for 3-4 min with e-brake on - when I release e-brake the light goes off rigth away.
What it might be?

Power Steering Fluid or Brake fluid is low and expanding with heat so it turns the light off

The brake light is used for multiple things. Handbrake is one of them. Another is low hydraulic pressure. (Others: low brake fluid, low hydraulic fluid.)

I had similar symptoms (brief illumination of BRAKE light at startup) and they went away after I did a hydraulic fluid flush.

My car has been doing the same thing for over a year now and I'm very sure I'm not low on any fluids.

So you just flush/bleed brake fluid without replacing bomb?
