Does it occur on specific slopes? Does the click noise occur before application of the brakes, during the initial application of the brakes, during the short moment before stopping, during the actual stop, or after lifting off the brake pedal to launch?
Also, are there any warning lights illuminated on your vehicle's instrument panel so far?
