hi everyone, im new to the site and have a few questions about the brake booster. it sounds like i have a loud air leak coming from primarily under my dash while the jeep is running and when i press the pedal the leak gets quieter. is this normal or is the seal bad on the booster? engine idles decent when its warm but not cold. also i did the pedal test with the jeep off and started the engine and the pedal moves about a 1/2 inch nothing more... so is it kind of working? or should should it move farther?
thanks
thanks
