摩擦材料のサービス寿命（セラミックブレーキパッド）は、もう1つの重要な要件です。摩擦材料の種類と使用条件に応じて、要件も異なります。たとえば、カーブレーキパッドには何キロメートルの走行距離が必要ですか？
摩擦ペアの摩耗は、ブレーキ状態の悪化の主な理由です。 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.他の一致する部分の摩耗は、摩擦ペアの摩耗にも影響します。 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.
摩耗は、摩擦条件と摩擦状態に依存します。 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.摩擦の不均一性は、ブレーキ圧の分布を変化させ、摩擦ペアの不均一な摩耗を増加させます。 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.
