"Small problem" type brake abnormal sound
1. Brake disc run-in period
No matter the new car brake or newly installed brake disc, in the early use of the state has not yet reached a relatively consistent with the brake shoe, when the brake, heavy brake may appear sharp abnormal sound, this is normal, do not worry too much, is not a fault. If you care, it is recommended that the owner of the car during the run-in try to avoid heavy brake, brake.
2. Rebrake continuously
Excessive use of the brakes for a short period of time or continuous heavy braking, the brake disc overheating, braking power reduction, is a "thermal attenuation". The specific manifestation of thermal attenuation is significantly weakened braking force, brake will appear sharp abnormal sound. These two cases are also the normal performance of brake thermal attenuation, not fault, when the thermal attenuation disappears, abnormal sound will disappear.
"Attention needed" brake abnormal sound
1. Metal particles appear on the brake pad
Some of the original brakes are still made of semi-metal materials, and wear can lead to uneven distribution of high-hardness metal particles. When they are spread across the brake pad, the abnormal sound between the metal particles and the brake disc begins.
Although there is no serious damage, wear a period of time metal particles will disappear, but after all, there are some bad effects on the brake disc, cherish the car owners, or choose to replace better brake pads.

The thickness of the warning iron on the brake pad will directly rub with the brake disc, resulting in abnormal noise. The noise was loud and belonged to the unbearable kind. At this time, it is the time to replace, not only to replace the noise is huge, disturbing, braking force will be greatly reduced, hidden dangers increase safety.

The metal edge of the brake disc will be in direct contact with the brake pad, resulting in a huge abnormal noise, which may cause severe body shaking and brake failure. It is recommended that the owner of the car regularly check the thickness of the brake disc, the change, do not wait for excessive wear to change, inappropriate.
