How to Solve the Clicking Noise During Low-Speed Braking?
3 Answers
The solutions for clicking noise during low-speed braking are: 1. Check the wear condition of the brake disc and brake pads, and replace them in time if severely worn; 2. Reassemble the brake pads; 3. Clean foreign objects from the brake pads and brake disc; 4. Inspect and replace the caliper if necessary. The reasons for clicking noise during low-speed braking are: 1. Excessive wear of the brake disc and brake pads; 2. Improper assembly of the brake pads. The composition of brake pads includes: steel plate, adhesive heat insulation layer, and friction block. The heat insulation layer is made of non-heat-conductive materials to provide insulation; the friction block consists of friction materials and adhesives, which generate friction when pressed against the brake disc or drum to achieve vehicle deceleration and braking.
I've also encountered this low-speed braking clunking issue before. It's likely caused by uneven engagement between the brake pads and rotors. Last time I checked, I found the brake pads were wearing unevenly, with edges developing ridges that caused the clunking sound at low speeds. Actually, there's no need to panic, but it should be addressed promptly as it will only get worse with continued wear. You can first check the brake pad thickness yourself - if you notice significant uneven wear on both sides, they need replacement. If you can't handle it yourself, find a reliable repair shop to have the mechanic check for rotor warping. Sometimes a simple rotor resurfacing can solve the problem. Remember to pay special attention to the braking system during regular maintenance, especially if you frequently drive in congested areas, as brake pads wear out faster under such conditions.
A low-speed braking noise with a clunking sound is commonly caused by brake pad issues. Last time my car had the same problem, it was so annoying when moving the car in the neighborhood. At first, I thought a small stone got stuck, but the mechanic later said it might be due to the newly replaced brake pads being too hard, causing vibration noise when rubbing against the brake disc. Another possibility is insufficient lubrication of the guide pins—dry metal friction can produce that clunking sound. Actually, it's quite simple: first, go to the shop and have the brake pads removed to check if the backing shims are still in place. If they're missing, it can easily cause abnormal noises. If it's rained recently, the brake discs might also be rusty. It's best not to delay and get it checked early—it never hurts to be proactive.
