The service life of friction materials (ceramic brake pads) is another important requirement. Depending on the type of friction material and the conditions of use, the requirements are different. For example, how many kilometers are required for car brake pads?

The wear of the friction pair is the main reason for the deterioration of the braking state. The friction works in the form of a dynamic fit. The material loss of the friction surface gradually increases with the increase in the number of uses. The wear accumulation will gradually change the dynamic friction pair. Characteristic parameters, reduce work capacity. The wear of other mating parts also affects the wear of the friction pair. For example, the uneven wear of the brake cam affects the lift of the cam, which in turn affects the displacement of the shoe, until it affects the contact between the friction material and the counterpart.

Brake pad wear

Wear depends on the friction conditions and the state of friction. Friction materials are mostly in the form of dry friction. This non-lubricated friction condition is a harsh condition for the friction pair, which will inevitably cause wear and increase the fit gap, which will affect the braking performance. In general, the wear of the friction pair is uneven wear, and the wear gap caused by all wear is also uneven. This unevenness is prominent on drum brakes. The unevenness of friction changes the distribution of brake pressure and promotes uneven wear of friction pairs.

In addition, the increase in friction during braking and the ingress of dust from the operating environment into the friction pair will cause the process of driving wear. This wear is caused by thermal wear, abrasive wear, adhesive wear, and fatigue wear at the same time, that is, wear is inevitable. But the amount and speed of wear can be controlled, because the speed of wear depends on the number and frequency of use, intensity of use, use environment and use level.
