Why Does the Automatic Transmission Brake Make Noise?
1 Answers
When the automatic transmission brake makes noise, the main reasons are as follows: 1. The brake pads and brake discs are new and still in the break-in period: New brake pads and discs may produce noise, which will disappear after driving a few hundred kilometers. 2. There are foreign objects between the brake pads and brake discs: Strong wind or small particles like sand or small stones may enter between the discs and pads. 3. Rainy days or water inside the brake discs make the brake pads and discs damp: At low speeds, the brakes may vibrate and make noise, which will return to normal after the water dries. 4. Changes in tire friction patterns: When braking in reverse, the friction patterns change. Since the car usually brakes while moving forward, the reverse friction patterns may cause unusual noises. 5. Noise caused by ABS activation: This occurs during emergency braking, and such brake noise is completely normal, often accompanied by vibration of the brake pedal.
