What Is a Better Friction Coefficient of Drum Brake Pads Under High Temperature?
In the national standard, there is a clear definition of the high temperature friction coefficient, which cannot be lower than
0·25, but also to ensure that it is within the specified friction coefficient. If a product, The specified friction coefficient is 0.4, when you see the product inspection report, 350 ° C The coefficient of rub is 0.25, although it reaches 0.25, but the national standard requires this moment, The coefficient of friction is not less than 0.4 - 0.12 = 0.28. This product is also not suitable
