    Installation and Repair Tips
    Q:
    How do you perform an airtightness check on the Brake Booster and brake system for the 2007 Chrysler Town & Country? Posted by Customer
    A:
    Start the engine and turn it off after a minute or two, then depress the brake pedal slowly. If the pedal initially goes down farther but gradually rises with subsequent depressions, the booster is airtight. Additionally, depress the brake pedal while the engine is running, then stop the engine while holding the pedal down. If there's no change in pedal reserve travel after 30 seconds, the booster is airtight.

    Q:
    How do you install the power Brake Booster unit for the 2003 Dodge Caravan? Posted by Customer
    A:
    To install the booster, position it on the firewall and tighten the retaining nuts. Reconnect the brake pedal to the booster pushrod with a new retainer clip, and perform the remaining installation steps in reverse, ensuring a new vacuum seal is installed on the master cylinder before reattaching it to the booster.

    Q:
    How can you perform an operating check on the power Brake Booster, and what are you checking for for the 2005 Dodge Grand Caravan? Posted by Customer
    A:
    To perform an operating check, first, depress the brake pedal several times with the engine off and make sure there's no change in the pedal reserve distance. Then, depress the pedal and start the engine. If the pedal goes down slightly, it is considered normal operation.
