What Causes the Clicking Sound When Braking in an Automatic Transmission Car?

[DeAlan]

Automatic transmission cars may produce abnormal sounds when braking due to normal ABS activation or electronic linkage. Here are the detailed explanations: Normal ABS Activation: The ABS operation is actually a cyclic process of locking and releasing the brakes, keeping the vehicle in a state of near-lock intermittent rolling. When you brake hard and trigger the ABS, it may produce a clicking sound, which is normal. In this case, simply press the brake pedal firmly to the floor. Clicking Sound from the Gear When Braking in an Automatic Transmission Car: If you hear a clicking sound between the transmission and the gear lever when pressing the brake pedal, the main cause may be the electronic linkage between the braking system and the automatic transmission. When the brake is pressed, the transmission solenoid valve activates, producing a clicking sound. This serves as a safety reminder, as you need to press the gear lever lock button to shift gears.
