What Causes the Noise When Pressing the Brake Pedal in a Sedan?

[SabrinaAnn]

Brake noise when pressing the pedal may be due to normal ABS operation, safety reminders, loose chassis components, or unstable brake discs. The details are as follows: 1. The ABS working process is actually a cycle of locking-releasing-locking-releasing, keeping the vehicle in a critical locked state with intermittent rolling. When you press the brake pedal 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. 2. If you hear a 'click' sound between the transmission and the gear lever when pressing the brake pedal, the main reason could be the electronic linkage between the brake system and the automatic transmission. Pressing the brake activates the transmission solenoid valve, producing the 'click' sound. This is a safety reminder, and you need to press the gear lever lock button to shift gears. 3. If you hear a clicking noise even with light braking, or if your vehicle doesn't have an automatic transmission lock button, or if the noise is continuous or frequent, you should be cautious. It is highly likely due to a brake system malfunction or loose connecting components in the chassis.
