Power Brake Booster

Post by redbaron05 »

I hear like an air 'hissing' noise every time I step on the brake pedal. This started about a week ago. I looked under the dash and localized the sound to the back of the booster in that gray bellows thingy. Researching this on the internet, seems like the booster is the culprit....2003 Black Sapphire and I are going to change the booster this weekend. Has anyone else had this problem?
