    Q:
    How do you perform an operating check on the brake system, including the Brake Booster, of the 2014 Cadillac CTS? Posted by Dorian Y.
    A:
    Start by depressing the brake pedal multiple times with the engine off to ensure there is no change in the pedal reserve distance. Then, depress the pedal and start the engine, noting if the pedal goes down slightly, indicating normal operation. You can Select Your Vehicle to see complete installation and repair tips.
