    Q:
    How do you perform an air tightness check on the Brake Booster for the 2002 Jeep Liberty? Posted by Iain F.
    A:
    Start the engine and turn it off after one or two minutes. Slowly depress the brake pedal several times and observe if the pedal goes down farther the first time but gradually rises after the second or third depression, indicating an airtight booster. Additionally, depress the brake pedal while the engine is running and stop the engine with the pedal depressed. If there is no change in the pedal reserve travel after holding the pedal for 30 seconds, the booster is airtight. You can Select Your Vehicle to see complete installation and repair tips.
