Why are there holes in the new brake pads?
The organic matter and resin on the surface of the friction material of the brake pad will form an air cushion during the initial braking process, which will reduce the braking performance. The instantaneous high temperature of the ablation process can decompose and volatilize the organic matter and resin, which is beneficial to the real "useful" friction material to be exposed as soon as possible and to exert its effect.
Ablation is the core part of the brake pad production process, and the temperature of the high-temperature ablation machine can rise to about 700°C instantaneously.
Brake pad ablation process
Reduced break-in period: Improves initial braking performance, shortens break-in period, and ensures good pedal feel from the first brake.
Reduce thermal fading: thermal fading means that after the working temperature of the brake pad rises to a certain level, the braking effect will rapidly decrease. After the brake pads have undergone high temperature and deep ablation in the early stage, they can immediately enter the working state to ensure the long-term stability of the brake.
Improve safety: improve the initial braking performance and reduce the initial braking distance.
To sum up, the pores and high-temperature traces on the surface of the brake pads are formed by the ablation process, which not only does not affect the braking force, but also guarantees high performance.
Now, whether it is a European car or a Japanese car, it has become a trend to ablate the original brake pads.
