The Dodge Avenger utilizes a disc brake system on all four wheels, with the front brakes typically handling the majority of the stopping power. The front brakes are designed to wear down faster than the rear brakes, and it's recommended to inspect and potentially replace or resurface the rotors every 5,000 to 10,000 miles. The rear brakes, while not handling as much stopping force, are also important and should be inspected regularly.
