Brake pad knowledge: one question every day

What is the relationship between the life and hardness of brake friction pads?


There is no certain relationship between the life of brake pads and surface hardness. However, if the surface hardness is high, the actual contact area between the brake pad and the brake disc is small, which often affects the service life. The main factors that affect the life of brake pads include hardness, strength, and the wearability of friction materials. Under normal circumstances, the service life of the front brake friction pad is 30,000 km, and the service life of the rear brake friction pad is 120,000 km.
