1999 Chrysler LHS Q&A
1999 Chrysler LHS Question: Brake power booster
The booster is the device that provides your power brakes, it makes stopping a lot easier. It does this with vacuum from the engine, and when the booster leaks, you will hear the noise you are describing. The booster is on the firewall, right behind the master cylinder. Here is a picture of one, not your car but it will be similar: http://www.trustmymechanic.com/parts_gallery/brake_booster.jpg - Bret Bodas
