Gents, I have a mystery noise every time I press and release the brake pedal. Its a creaking sound. If the sound were a squealing sound, I wouldn't be asking for your help since I could diagnosis that. I can't find Squat on the internet, and what I do find, some say it could be the master cylinder or brake booster. What could cause a creaking sound just by depressing the brakes?
