Temperature is an important factor affecting friction coefficient. Friction materials in the process of friction, due to the rapid rise of temperature, the general temperature of 200℃ or more, the friction coefficient began to decline. When the temperature reaches the decomposition temperature range of resin and rubber, there is a sudden decrease in friction coefficient, which is called "thermal recession". Severe "thermal decline" can lead to poor braking performance and deterioration. In practice, this reduces friction and thus braking, which is dangerous and must be avoided. Adding high temperature friction regulator filler into friction material is an effective means to reduce and overcome "thermal decay". After "thermal recession" of the friction plate, when the temperature is gradually reduced, the friction coefficient will gradually return to the original normal situation, but sometimes the friction coefficient recovery is higher than the original normal friction coefficient and recovery is too much, for this friction coefficient recovery is called "over recovery".
