What Causes the Clicking Sound When Pressing the Brakes?
2 Answers
Reasons for the clicking sound when pressing the brakes are as follows: 1. New car or newly replaced brake pads: It's normal for new cars or newly replaced brake pads to make noise initially, as the friction surfaces haven't fully matched yet. The sound will automatically disappear after driving a few hundred kilometers for proper break-in. 2. After getting wet from rain: Brake pads, mostly made of iron, can rust when exposed to rain, causing noise when braking. The sound will go away once the rust is worn off. 3. Brake pad configuration issues: Abnormal brake pad configuration may include incorrectly installed brake pads, missing screws or components, brake pads that are too small and don't match the friction surface, or the use of cheap brake pads.
I've also experienced the annoying clunking sound when braking in my old car. Common causes could be brake pads worn to the limit, where thin pads slide unevenly on the disc causing vibration. Or the brake disc surface might be rusty, especially after being parked for a long time in the rain—a few brake applications usually improve it. Another possibility is insufficient lubrication of the brake caliper guide pins, making movement less smooth. If the clunking comes with steering wheel shaking, the disc is more likely warped. Worn suspension components like shock absorbers or ball joints can also transmit this sensation, making the whole car feel unstable. I suggest not delaying and getting it checked at a professional shop ASAP, as brakes might fail in emergencies. During regular car washes, simply wipe the brake components to prevent dust buildup and potential failures—safety is no small matter.
