4. The friction coefficient of the friction coefficient is too high or too low will affect the brake performance, especially in the high-speed emergency braking, the friction coefficient is too low will appear insensitive, the friction coefficient is too high will appear tire lock hadysalar. According to the SAE standard, the friction plate will choose the FF grade rating coefficient, that is, the friction rating coefficient is 0.35 ~ 0.45. In addition, according to the national standard, the appropriate working temperature of the friction sheet is 100 ~ 350 ° C, and the coefficient of friction will drop sharply when the inferior temperature reaches 250 ° C, and there is a failure.
