I have a sound from which seemed to vanish in the winter and spring ,( probably because of the cold weather i couldn't hear it anymore).
Now, that's hot outside is back again and it's driving me crazy.
After I'm driving for 15 min to half an hour, i can hear a weird whistle coming from the brake paddle after I'm taking off my foot and the brake paddle is depressing come back to the normal position. I can hear it even I'm driving or when I stop, turn the engine off and i step out of my car. I will leave two links of the videos with the car stopped... one with engine on and one with the engine turned off.

I'll get back with some videos while the car id running.
