What are the reasons for the abnormal noise in the rear brake of the UY125?
1 Answers
The reasons for the abnormal noise in the rear brake of the UY125 are as follows: 1. Break-in period for new vehicles: New vehicles or recently replaced brake discs and pads will have a break-in period, during which some abnormal noises are unavoidable. These noises typically disappear after driving a few hundred kilometers. 2. Normal activation of the ABS system: During emergency braking, the brake pedal may produce a continuous "thudding" sound, sometimes accompanied by a pulsating sensation. This indicates that the ABS system is activated, which is normal. In such cases, firmly press the brake pedal all the way down, but this applies only to vehicles equipped with an ABS system. 3. Metal hard spots on the brake pads: Brake pads may contain small metal particles, which can produce sharp, screeching noises when lightly braking. This issue can be resolved by forcefully applying the brakes several times, removing and regrinding the brake pads, or replacing them with higher-quality ones. 4. Severe wear on the brake disc: Wear on the brake disc can create deep grooves around its circumference. Friction between the brake pads and the edges of these grooves can cause abnormal noises. If the grooves are not too deep, grinding the edges of the brake pads to avoid contact with the groove edges may solve the problem. If the grooves are very deep, replacing the brake disc is necessary. Generally, it is recommended to replace the brake disc every two brake pad replacements.
