In order to study the relationship between the moisture behavior in friction materials and corrosion stiction and lowfrequency noise, the moisture behavior in the friction material was investigated and Fick’s 2nd law was introduced to simulate the moisture diffusion phenomenon in the friction material. From this, the diffusion coefficient of moisture and maximum moisture content in the friction material could be quantified, and it was also confirmed that the moisture behavior in the friction material was divided into a section following Fick’s 2nd law and a section not following Fick’s 2nd law. The results of the specimen moisture uptake test and corrosion stiction test showed that in the case of the NAO friction material, the larger the diffusion coefficient and the smaller the maximum moisture content, that is, the faster the friction material surface was saturated, the more unfavorable it was for corrosion stiction. Finally, the results of the specimen moisture uptake test and low frequency noise test showed that the larger the maximum moisture content of the NAO friction material, that is, the more moisture could continuously diffuse from the inside of the pad to the surface during braking, the more advantageous it was for the low frequency noise, and this can also be explained by the hydrodynamic lubrication theory. However, it is thought that further research is needed on the effect of the transfer film formed after friction material burnishing.
