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?

　　剎車片磨損感應是什么原理？

　　What is the principle of brake pad wear induction?

　　帶剎車片感應器的車型又分為兩種，一種是內藏式剎車片，望文生義就是感應線和剎車片一體的，每次改換只需購置剎車片。

　　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.

　　另一種則是剎車片和感應線是分體的，值得一提的是，假如在剎車片報警前改換剎車片的，無需改換感應線，假如一旦磨損到感應線位置觸發剎車片報警燈，就需求改換新的感應線了。

　　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.

　　不帶剎車片感應器的車型怎樣判別？

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

　　那些沒有剎車片感應器的，也不用擔憂，由于絕大局部的剎車片都帶有“聲音報警”。假如在輕點剎車的同時隨同有“鐵蹭鐵”的咝咝聲，就需求思索能否為剎車片磨損已到極限了。

　　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.

　　和普通的剎車異響聲音不同，當剎車片磨損到極限位置時，擔任磨損警示的鐵片會與剎車盤接觸并產生持續性的嘶嘶噪音。也就是說，當剎車片磨損已達極限時，任何時間、任何力度踩剎車，都會產生“鐵磨鐵”的聲音。

　　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.

　　事實上，即便你的剎車片磨損到了鐵制背板，照舊不會呈現沒有剎車的狀況。只是會存在剎車間隔變長、變軟、噪音大、傷剎車盤的狀況。

　　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.
