Hi, I have a 2000 Renault Megane 1.4L. Recently brake fluid has been leaking from the top of the container where you top up the brake fluid. I have not topped up the level recently (ages ago in fact!!)
Quite surprisingly, the brake fluid level has gone up as well, without any top up.
Can anybody daignose this particular problem?

Additional info: The brakes feel perfectly fine when you brake and recently I have had the hand brake adjusted.
Can anybody daignose this particular problem?

The problem is that you have over filled the reservoir, it should be just over half full when filled to the correct level as per the marks on the side of the tank itself.
Adjusting the handbrake has pushed the rear wheel pistons back into the cylinders and pushed even more fluid back into the reservoir.
You need to remove some of the fluid, but as you don't seem confident/competent. I would suggest a garage or qualified person does the work for you.

Have you felt a difference in the way the brake pedal feels? Has it become spongy feeling or has braking performance become worse? It sounds like somewhere you have an air leak, after you push the brakes and the brake pedal returns - the fluid pulls back and pulls the brake components (cylinders/calipers) with it. If air is bleeding in, it will increase the volume in the system and raise the level in the master cylinder (container you spoke of). I would suspect your problem is near to the brake booster or master cylinder, not so much out by the wheels or in a brake line. You should follow procedure for bleeding your brakes/master cylinder, if problem reoccurs - you have an issue with one of the parts in your brake system obviously.

9 times out of 10 you just ahve some air in your lines. It isn't too hard to do with yourself and a friend to sit in the car. Google break bleeding proccess. If this doesn't fix it, then your brake master cyclinder is probably at fault. It is a cheap part that you can also replace yourself if mechanically inclined. Hope this helps

Has the weather warmed up?? Liquid expands with temperature. That's why the full line on the reservoir is down a bit from the top on the container. You may have over filled the reservoir. Also check the condition of the rubber diagram /gasket they go bad.

Brake fluid expands with heat ,(heat from brakes from normal use transfers to the fluid) leave a space at the top for that expantion

You have air in the brake system. You need to have a mechanic,(one You know and trust) bleed the brake system.

If the brakefluid has not been changed for some time it may be water in the system.This happens when brakefluid breaks down due to been past its "sell by date"!.
