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.
