What causes the braking noise in GAC Trumpchi GS4?
2 Answers
There are several main reasons for the braking noise issue in Trumpchi GS4: 1. Running-in period for new cars: New cars or newly replaced brake discs/pads require a running-in period, during which some noise may occur. This usually disappears after driving a few hundred kilometers. 2. Normal ABS system activation: During emergency braking, the brake pedal may produce continuous sounds and sometimes a pulsating sensation, indicating ABS system activation. This is normal - simply press the brake pedal firmly all the way (only applicable to vehicles equipped with ABS). 3. Metal hard spots on brake pads: If there are small metal particles in the brake pads, they may produce sharp, screeching sounds during light braking. This issue can be addressed by forcefully applying the brakes several times, removing and resurfacing the brake pads, or replacing them with higher-quality ones.
When driving the GAC Trumpchi GS4, I've experienced squeaking noises during braking, which are usually caused by common mechanical issues. Brake pad wear is the most frequent cause. For someone like me who has driven the car for several years, if the brake pads aren't replaced regularly and their thickness reaches the limit, they can produce a metallic scraping sound. Other possible causes include uneven or warped brake rotors, which create noise during driving due to irregular surfaces, or small stones or debris stuck in the braking system, causing noise when the wheels rotate. Environmental factors also play a role—brakes are more likely to squeak in rainy or dusty conditions. I recommend first checking the brake pad thickness; if it's below 3mm, it's time for a replacement, especially since the GS4's braking system is designed to be economical and the materials wear out more easily. If the issue persists, it could be due to loose calipers or insufficient brake fluid, in which case a professional inspection is necessary. Don't wait until there's a potential hazard—safety should always come first in daily driving.
