Ang buhay ng serbisyo ng mga materyales sa alitan (ceramic preno pads) ay isa pang mahalagang kinakailangan. Depende sa uri ng materyal ng alitan at ang mga kondisyon ng paggamit, naiiba din ang mga kinakailangan. Halimbawa, gaano karaming mga kilometro ng mileage ang kinakailangan para sa mga pad ng preno?
Ang pagsusuot ng pares ng alitan ay ang pangunahing dahilan para sa pagkasira ng estado ng pagpepreno. Friction works in the form of dynamic fit, and the material loss of friction surface gradually increases with the increase of the number of uses. When the wear accumulates to a certain extent, the characteristic parameters of dynamic friction pair gradually change and the working capacity is reduced. Ang pagsusuot ng iba pang mga bahagi ng pagtutugma ay nakakaapekto sa pagsusuot ng mga pares ng alitan. 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 pair.
Ang pagsusuot ay nakasalalay sa mga kondisyon ng alitan at estado ng alitan. The friction material is mostly in the form of dry friction, and this friction condition without lubrication is a harsh condition for the friction pair, which will inevitably cause wear and increase the matching gap, and affect the braking performance. And under normal circumstances, the wear of the friction pair is uneven wear, and the wear gap caused by all wear is also uneven, which is prominent on the drum brake. Ang hindi pagkakapareho ng alitan ay nagbabago sa pamamahagi ng presyon ng preno at pinatataas ang hindi pantay na pagsusuot ng mga pares ng alitan. In addition, the friction heating of the braking process and the dust of the operating environment into the friction pair will cause the process of driving wear, which is thermal wear, abrasive wear, adhesive wear, fatigue wear and so on play a role at the same time, that is, wear is inevitable. However, the amount and speed of wear can be controlled, because the speed of wear depends on the number and frequency of use, the intensity of use, the use environment and the level of use.
