Re: what do you mean - calipers seize/overheat, and you cant move car?
I made a test, I just turned on the car without driving or pressing the breaks after 20 mins the breaks clamp on and the car is stuck solid, I jack up the car and each wheel is clamped solid

Oh no, Unintended Decelleration! Two possibilities as I see it.
First, is the brake pedal ALL the way up? You could have a brake master cylinder that is not allowing the fluid to return to the reservoir either due to linkage misadjustment (likely), a blockage (BTDT, but usually doesn't affect all wheels), sticking piston assembly (BTDT), or a brake booster problem.
Second (unlikely), the ABS system could be severely malfunctioning. I have seen two ABS units that were full of water and causing all kinds of strange behavior. Unplug the ABS unit in the engine compartment to eliminate this possibility.
If you are asking these questions, I would assume that you are not likely going to be the one fixing the problem. The best advice would be to get the car to a shop. This should be a very simple diagnosis, but not likely an inexpensive repair.

Not IME. Even if there was water in it, it shouldn't cause that problem.
My guess is that the master cylinder is sticking or not being allowed to return fully (for whatever reason, which must be checked) from a partially depressed condition, thereby not allowing the fluid to return to the reservoir. This is just a guess from my experience. I would highly recommend having a professional check it out.
