OK, I don’t know what it is but every time I release the brake pedal, there’s this hissing sound like leaking air coming from the below the dash near the brake pedal. It actually started a few months ago and comes and goes and was very minor but now it’s louder and happens every time the brake pedal is released. The hissing sounds continues even after my foot is completely off the brake and I’m on the gas pedal. It hisses for a while and when I step on the brakes again it stops but then starts up once I start releasing the brakes again.
Anyone know wtf is going on?
