    Q:
    How can you check the Brake Booster for the 2010 Cadillac DTS? Posted by Gion K.
    A:
    To check the brake booster, sit in the driver's seat and perform a series of tests: - With the brake fully depressed, start the engine and observe if the pedal moves down slightly. - With the engine running, depress the brake pedal several times, ensuring the travel distance does not change. - Then, depress the brake, stop the engine, and hold the pedal in for about 30 seconds, checking that it neither sinks nor rises. - Restart the engine, run it for about a minute, turn it off, and firmly depress the brake several times, noting that the pedal travel should decrease with each application. If the brakes do not operate as described, the brake booster has failed. You can Select Your Vehicle to see complete installation and repair tips.
