求翻译：造成刹车失灵的原因很多 ，一是对刹车系统缺乏必要的保养 ，刹车总泵里杂质太多 、密封不严 、真空助力泵失效 、刹车油过脏或几种刹车油混合使用受热后出现气阻 、刹车总泵或分泵漏油 、储气罐或管路接口漏气；二是由于操作不当导致机件失灵 ，如长时间下坡会使刹车片摩擦生热 、刹车毂炭化 、刹车功能完全失效；三是由于严重超载 ，在重力加速度的作用下 ，加大了车辆运动惯性 ，直接导致刹车失灵 。是什么意思？

Brake failure caused by many reasons, one of the brake system lacks the necessary maintenance, brake master cylinder in too many impurities, Mifengbuyan, vacuum booster pump failure, brake oil brake fluid is too dirty or mixed with several heated air resistance after , brake master cylinder or wheel
