This time, we are talking about brake pad wear warning lights and hand brake lights in all brakes. The function of hand brake lights is known to all. It reminds the driver that the hand brake has not been released. But besides, it also has a function. Can anyone guess?

　　刹车片磨损感应是什么原理？

　　What is the principle of brake pad wear induction?

　　带刹车片感应器的车型又分为两种，一种是内藏式刹车片，望文生义就是感应线和刹车片一体的，每次改换只需购置刹车片。

　　There are two types of car with brake pad sensor. One is the brake pad with built-in brake pad. Wangwensheng means that the induction line and the brake pad are integrated. Only the brake pad is needed for each change.

　　另一种则是刹车片和感应线是分体的，值得一提的是，假如在刹车片报警前改换刹车片的，无需改换感应线，假如一旦磨损到感应线位置触发刹车片报警灯，就需求改换新的感应线了。

　　The other is that the brake pad and the induction line are separated. It is worth mentioning that if the brake pad is changed before the brake pad alarm, there is no need to change the induction line. If the brake pad alarm lamp is triggered when the induction line is worn out, a new induction line will be needed.

　　不带刹车片感应器的车型怎样判别？

　　How to distinguish the type of car without brake pad sensor?

　　那些没有刹车片感应器的，也不用担忧，由于绝大局部的刹车片都带有“声音报警”。假如在轻点刹车的同时随同有“铁蹭铁”的咝咝声，就需求思索能否为刹车片磨损已到极限了。

　　Those without brake pad sensors need not worry, because most of the brake pads have a "sound alarm". If there is a click of "iron rubbing" accompanied by a light brake, it is necessary to consider whether the wear of the brake pads has reached its limit.

　　和普通的刹车异响声音不同，当刹车片磨损到极限位置时，担任磨损警示的铁片会与刹车盘接触并产生持续性的嘶嘶噪音。也就是说，当刹车片磨损已达极限时，任何时间、任何力度踩刹车，都会产生“铁磨铁”的声音。

　　Unlike ordinary abnormal brake noise, when the brake pad wears to the limit position, the iron pad acting as the wear warning will contact the brake disc and produce continuous hissing noise. That is to say, when the wear of the brake pad reaches its limit, the sound of "iron grinding" will be produced whenever and whenever the brake is pressed.

　　事实上，即便你的刹车片磨损到了铁制背板，照旧不会呈现没有刹车的状况。只是会存在刹车间隔变长、变软、噪音大、伤刹车盘的状况。

　　In fact, even if your brake pads wear down to the iron backplane, they will still not appear without brakes. But there will be longer, softer, louder noise and damage to the brake disc in the brake workshop.
