How to Solve the Brake Noise Issue in Kia Sportage?
2 Answers
Noise is more likely to be caused by brake pad issues. Severe wear, metal particles, or improper installation could all lead to noise. Additionally, in winter, the rubber components of the brake suspension may harden due to low temperatures, causing noise that naturally disappears once the car warms up. Below are the possible causes of brake noise: If the noise is a low-pitched thud, it might be the sound of the ABS (Anti-lock Braking System) activating. After ruling out the ABS, consider whether the cold weather is causing the brake rubber pads to deform, leading to misalignment and noise. If the noise disappears after driving for a while, this is likely the case. However, there are many potential causes for brake noise during startup, most of which are related to brake pads. Severe wear or improper installation of brake pads could cause noise. Other possibilities include issues with the brake caliper, wear on the brake pad pins, or detachment of the brake pad spring clips, all of which could also result in noise.
I found it really annoying when my Kia Sportage made strange noises while braking. Once, my car squeaked during low-speed turns, and I initially thought it was a minor issue and ignored it. Later, after checking some information and asking a few experienced driver friends, I learned that common causes could be excessive brake pad wear or rust on the brake discs. A simple self-check is recommended first: find a flat area to park, close the windows, and listen for the source of the noise. If the sound only occurs when the car is cold, it’s mostly due to disc oxidation—just drive a few kilometers and apply the brakes a few times, and the noise should stop. If the noise persists, the brake pads might be too thin, so quickly visit a repair shop to measure them. If they’re below 3mm, they need replacement. Don’t delay—safety comes first. If the brakes fail during an emergency stop at high speed, the consequences could be severe. I replaced the pads back then and did some maintenance, and the noise never came back.
