What Causes the Clicking Sound and Jerking Sensation When Braking?
3 Answers
The main reason for the sound may be the electronic linkage between the braking system and the automatic transmission. When the brake is pressed, the transmission solenoid valve opens and produces a "clicking" sound. At this point, the gear shift lock button must be pressed to engage the gear, which serves as a safety reminder. Here are the possible reasons for the clicking sound and jerking sensation when braking: 1. Normal ABS activation. The ABS operates in a cycle of locking and releasing, keeping the vehicle in a state of near-lock rolling. When you brake hard and trigger the ABS, it produces a clicking sound, which is normal. In this case, simply press the brake pedal firmly to the floor. 2. The "clicking" sound from the gear shift in automatic transmission vehicles when braking. If you hear a "clicking" sound between the transmission and the gear shift when pressing the brake pedal, the main cause may be the electronic linkage between the braking system and the automatic transmission. Pressing the brake causes the transmission solenoid valve to open, producing the sound, and the gear shift lock button must be pressed to engage the gear—this acts as a safety reminder. 3. Actual malfunction. If the clicking sound occurs even during light braking, or if your vehicle lacks an automatic transmission lock button, or if the sound is continuous or persistent, be cautious. This likely indicates a fault in the braking system or a loose component in the chassis. For safety reasons, the owner should promptly visit a 4S shop for inspection and repair.
As an experienced driver, I've encountered this kind of issue with grinding noises and jerky braking quite often. It's mostly caused by problems with the brake discs. If the disc surface is rusty or unevenly worn, you'll hear that grinding sound when braking, accompanied by a jerky sensation throughout the car body, almost like it's trembling. If not addressed promptly, braking performance will be significantly compromised, making driving downright nerve-wracking. My own car had this issue particularly noticeable during rainy days, and upon inspection, the discs were severely warped with uneven rust spots. I'd suggest you first check the thickness of the brake pads - if they're too thin, replace them immediately. Also, inspect the brake fluid for contamination or air bubbles, as these can worsen the jerking. Don't delay; take it to a reliable repair shop or dealership for a comprehensive diagnosis to ensure the ABS system is functioning properly. After all, safety comes first. Remember to perform regular maintenance - prevention is better than cure.
As a car repair enthusiast, I think brake noise and jerking are quite common issues. For example, uneven brake discs can cause vibrations and clunking sounds when the pads rub against them; loose caliper mounts may also lead to squeaking. As for the jerking sensation, like it's getting stuck, it's usually due to brake fluid leakage or rusted caliper pistons. Last time I took mine apart, I found loose screws—tightening them fixed the problem. But deeper issues, like too much dust on the ABS sensor, can also trigger it. Before working on it, always ensure the car is parked and the engine is off, and visually inspect the wear on the discs and pads first. If it's beyond your skill, don't push it—get a professional to take a look. Maintaining regular check-ups and cleaning the oil lines can prevent many minor issues.
