What Causes the Clicking Sound When Braking Right After Starting the Car?
2 Answers
The reasons for the clicking sound when braking right after starting the car are as follows: 1. Excessive wear of the brake disc and brake pads. Both the brake disc and brake pads are high-wear components, as they rub against each other every time the brakes are applied. Over time, wear naturally occurs, and when it becomes excessive, abnormal noises can result. 2. Improper installation of the brake pads. If the brake pads are installed incorrectly or are of the wrong model, abnormal noises may also occur. The brake pads may need to be reinstalled. When installing brake pads, it is advisable to have the work done at a professional auto repair shop. 3. Normal operation of the ABS. The working process of the ABS is actually a cycle of locking and releasing, keeping the vehicle in a state of near-lock rolling.
Just started the car and there's a clunking sound when stepping on the brakes. I've been in the automotive industry for years and seen this issue countless times. In cold conditions, metal components contract, causing brake pads to harden and deform, creating noise during friction. It could also be due to rusted or sticky calipers that aren't moving smoothly, or misalignment causing uneven pressure on the brake disc. The sound is especially noticeable in winter when temperatures drop. In areas with heavy rainfall, rust buildup can also cause this. I recommend warming up the car for a minute or two and gently applying the brakes a few times after driving off—if the noise reduces, it's fine. If the sound persists, have the brake system checked immediately; don't wait until braking distance increases and accidents happen. I've seen many car owners ignore this, only to spend big money replacing entire brake discs later.
