Here relates to brake heat fade and the ablation problem. Thermal recession means brake wagon (or brake disc) temperature rise in a certain degree, the braking effect is diminished or even failure phenomenon (this is very dangerous, the car can not stop where there are not the heaven's sake, therefore the critical temperature of thermal recession very important), obviously feeling is the brake foot soft, then how to step on the brake effect is not obvious. Different brake heat fade temperature is different, the original factory brake general at 250 DEG -280 DEG C, and good brakes should be at least 350 DEG C, which is more safe and you can imagine

hen the intensity and time of brake continues to increase, the temperature continues to rise, then the brake internal material will undergo chemical changes, causes the molecular structure to change and influence the braking effect, this is the so-called ablation. The mirror shape was ablated symptom is the leather shiny, it is the structure after the ablation of lining material high temperature crystallization. After the hot recession cooling brake will recover naturally braking capability, but ablation is not the same, it is not recoverable. Brake pads but the occurrence of the braking ability of ablation is nearly completely lost, for security and peace must be dealt with immediately, light weight of sanded and can only be
