My girlfriend is having issues with her brake booster. Its making a vacuum leak noise right under the pedal where the rubber shroud surrounds the inside part of the booster that connects to the brake pedal. I checked the vacuum line from the booster to the engine block in the engine bay and it looks fine. Was wondering if anyone on here would know a rough guestimate on how much it would be to replace the booster/anyone wanna do it.
