Why are there holes in the new brake pads?
Brake pad ablation process
Reduce the run-in period: improve the initial braking performance, shorten the run-in period, from the first brake to ensure a good feeling of the pedal.
Reduction of thermal recession: thermal recession refers to the brake effect will decrease rapidly after the brake operating temperature rises to a certain extent.After the high temperature and deep ablation in the early part of the brake pad, it can immediately enter the working state to ensure the long-term stability of the brake.
To sum up, the pores and high-temperature marks on the brake pad surface are formed by the ablative process, which not only does not affect braking force, but also guarantees high performance.
Now, whether European or Japanese cars, the original brake pad ablation has become a trend.
The organic matter and resin on the friction material surface of brake pad will form air cushion in the initial braking process, which will degrade the braking performance.The use of ablative process of instant high temperature can make organic matter and resin decomposition and volatilization, conducive to the real "useful"
