    Q:
    How do you perform an airtightness check on the brake system, including the Brake Booster, for the 2015 Lexus RX350? Posted by Casey H.
    A:
    Start the engine and turn it off after a minute or two. Slowly depress the brake pedal several times, and if each depression results in less pedal travel, the brake booster is airtight. To further confirm airtightness, depress the brake pedal while the engine is running and stop the engine with the pedal depressed. If there is no change in pedal reserve travel after holding it for 30 seconds, the brake booster is airtight. You can Select Your Vehicle to see complete installation and repair tips.
