Annoying sounds

[Maximus787]

Hi,
How can I get rid of the brake hiss sound?
I find the brake hiss really annoying and unrealistic. There is also another sound which sounds like a jet engine whine you hear when accelerating especially in WTCC cars. I think it is the transmission sound.
Here is a video of that sound: How do I remove it as well?
Can I remove these sounds for all cars at once or do I have to do them one by one?
Will it work if I just delete the .wav files? What's the easiest way to do it?

Thanks

Don't worry about it. I figured it out. It sounds so much better now to hear the pure engine sound while driving without the annoying transmission noise.
