如何消除汽车制动器打磨噪音

Have you been hearing grinding noise out of your car brakes? If yes, then it must be making you very anxious. It’s not only annoying to hear brakes grinding, but it can also damage your car further if you keep ignoring this warning sign.

Brakes are highly stressed component of a vehicle and it’s nothing to worry about if it makes some squeaking sound now and then. Ever heard a race car make a squeaking noise when brakes are applied gently? That’s perfectly normal for a race car because the high performance sintered brakes have a lot of metal in them. These brakes are meant to do one thing: To have a very strong bite on the rotor disk.

But regular passenger car brakes need to be noise free. Sometimes we might hear squeaky noise now and then which is normal.

当汽车在长时间后驾驶并且制动转子上有一些生锈沉积物后，这一点尤其注意到。在前几次制动应用程序后，这种生锈很快就会清除，这没什么可担心的。

但是，在制动时打磨噪音需要立即注意。如何检查？定期驾驶汽车，并一直刹车以停止（请确保在安全的环境中进行）。即使您增加制动器的压力，磨削仍在继续，因此您需要进一步研究它。

是什么引起制动磨削的噪音？

最likely suspect of brake grinding sound is worn out brake pads.这就是为什么建议立即停止并检查问题的原因。如果您无法弄清楚，请缓慢驱动到最近的自动机械师。也就是说，由于其他原因，磨的声音也可能出现。让我们讨论所有可能的概率：

1）用完的刹车片

正如我之前提到的，刹车垫完全磨损时，刹车发出的噪音通常会出现。将几毫米厚的制动材料融合在金属背板上。

当制动材料完全分配时，将靠背板推向转子。您可以想象，金属接触的金属接触在转子上非常粗糙。bepaly如何下载您绝对不想在制动转子上裸露金属刮擦。

如果您继续这样驾驶，首先您会失去大部分制动性能，您会损坏转子，如果您继续这样的驾驶，也可能会损坏制动卡钳。如果您的刹车片很好，并且您仍在听到磨损的声音，请继续阅读。

2) Foreign object stuck in the Braking System

Brake rotors and calipers are exposed to dust and grim all the time. But that’s perfectly normal. However, sometimes a big pebble or some other foreign object could get stuck in the braking system and rub against the brake rotor. This problem can be easily fixed by taking something like a screwdriver or even a pressure washer to pry out the foreign object.

3）刹车垫片受损

Brake pad shims are made out of metal and help keep the brake pads in perfect position in the caliper. They also make the brakes noise free. Theseshims有时会破裂并开始拖动转子。那时它会使刹车嘈杂。

Most people keep using the same shims for years and never replace them with brake pads. However, one should inspect shims every time brake pads are replaced. If you notice some wear, replace it with new shims and don’t wait for it to break and start causing problems.

4）磨损的车轮轴承

When wheel bearing wears out, it will make a grinding sound even when brakes are not applied. However, the noise can increase when you apply brakes. That’s because while braking, the bearings have to handle extra force. For the same reason, you’ll also notice that grinding noise will also come while taking a turn.

其他类型的制动噪音以及为什么会发生？

1）由于在公共道路上使用赛车刹车片而引起的噪音

一些驾驶爱好者想要每天骑车的最佳刹车片。这是值得称赞的，因为好刹车只会增加安全性。但是，不要误以为只使用轨道在公共道路上使用刹车片。

这些刹车片中有很多金属。在赛道上，刹车的温度非常高，这是它们表现良好的时候。是的，它们更快地磨损转子，但这是出色制动的成本。

当您在街道上使用它们时，出现了问题。这些垫子会不断发出尖叫声，不会提供良好的制动性能，因为它们永远不会在街上驾驶中达到最佳温度。

2）刹车垫磨损指示器在转子上摩擦

Most cars have brake pad wear indicator. On German cars, it’s an electronic system that flashes warning on the dashboard when the wear indicator contacts the rotor. In other cars, it’s just a piece of metal that rubs against the rotor and make a squeaking noise.

不要忽略此警告消息，因为如果您这样做，那么当制动垫材料完全磨损时，您会很快听到磨削的声音。

3）非润滑卡钳指南销

每当您按下刹车时，刹车片都会在卡尺导针。因此，建议在导向引脚上添加一轻油脂。这减少了摩擦，使制动垫在其上平滑滑动。

大多数机械师都跳过了这一步骤，即使到那时，制动器仍然没有噪音。但是，添加一层高温油脂是一个很好的预防措施。除此之外，油脂还减少了针上的磨损。

4）笨拙或重击刹车噪音

这种噪音很可能是由于悬架问题而不是制动问题所致。当您刹车时，汽车鼻子，然后回来。这可能会导致诸如不良支柱或震动之类的东西发出笨拙的声音。甚至丢失电缆的托架也可能是罪魁祸首。

Is it safe to drive with grinding brakes?

否。刹车发出的磨削声音绝对是一个标志，表明您应该慢慢开车并检查刹车垫。另一方面，尖叫声对于高性能烧结的刹车片是正常的。

Can you keep driving with worn brake pads?

Yes you can, but shouldn’t. Apart from being dangerous, it can also damage brake parts like rotors and callipers. $50 brake pad vs $500 brake parts. You choose.
