What Causes the Brake Noise in Trumpchi GS4?
2 Answers
The causes of brake noise in GAC Trumpchi GS4 are as follows: 1. New car break-in: The break-in of brake pads is a crucial process. Typically, after driving a few hundred kilometers, the brakes will feel more comfortable and the noise will disappear. 2. Sand in the brake disc: While driving, very fine sand particles may enter between the pad and disc, causing friction and resulting in noise. This usually does not require repair; simply driving a bit more can help the sand particles fall out. 3. Missing or damaged brake disc fixing screws: This can also cause brake noise. 4. Brake system malfunction: In this case, inspection and repair are necessary. 5. Brake disc wear: This occurs due to a dirty brake disc surface, uneven material density of the brake disc, excessively high working temperatures, or mismatched installation torque, leading to noise.
My Trumpchi GS4 brakes sometimes make a weird squeaking sound, which makes me curious about the reason. The most common cause is that the brake pads are worn too thin, making noise when pressed; if the brake disc surface has rust or scratches, it will also cause friction noise; for new cars or just after replacing the pads, the material hasn't been properly broken in, and excessive metal particles can cause loud noises. On rainy days, the humidity is high, and the water film on the brake disc increases, making the friction noise louder, but it will disappear after driving for a while, so no need to worry. More troublesome issues could be foreign objects stuck in the braking system or loose calipers not pressing tightly, which can cause persistent and worsening abnormal noises that need immediate repair. After experiencing this myself, I now check the pad thickness during every maintenance and ask the mechanic to clean dust buildup, which can prevent many minor issues. Remember, brakes are a matter of life and death, so don't overlook such details.
