Brake light and dashboard light beeping+engine cuts out
 

Hi,
Sometimes when i switch on the car i get the break (!) warning light and beep. I need to switch the key on and off a few times until it disappears otherwise it wont let me start the engine. The issue is even bigger, after i manage to start up the engine i sometimes get all the lights beeping and flashing and the engine cuts out. This issues occured only when i started the car and/or after a minute or two with the engine running.
Since two days ago this problem happens in the traffic as well, i get the dahsboard lights beeping and flashing and the engine cuts out.

This issue is very random i might get it 2-3 times a day or i might not get it at all. I am not very sure, but it seems that only when its warm outside it happens. Especially when the can was sat in the sun for a couple of hours. During ther night when the temperature is a bit lower i still get the (!) brake warning but after switching on and off a couple of times it disappears and the engine doesnt cut out.

Tried topping up the break fluid and it didnt work.

Thank you very much.

take the car to autozone and have them scan it.
