昨天有朋友问,他的刹车片保养师傅说要更换了,在哪里换最好,跟网上买得靠谱吗?
相信很多车主对汽车保养常识不是很清楚,今天给大家分享一下关于汽车刹车更换及刹车品质的问题,如何区分原厂和副厂的刹车片,避免多花冤枉钱。
在购买新车后,随着里程数的增加,汽车就需要按时的保养,这样才能让汽车保持最好的运行状态,避免发生交通事故。刹车作为磨损消耗件,在行驶中起着非常关键的作用,刹不住,刹车异响,刹车延迟等等,都会造成一定的安全风险,所以,作为车主,有必要了解一下汽车刹车的常识。
一、刹车工作原理
二、汽车刹车的工作原理很简单,通过刹车踏板产生压力,控制刹车片的收张,从而达到与刹车盘的摩擦来控制汽车的速度。
目前大多数的汽车装的都是鼓刹或者盘刹,其实不管是哪一种,它们的工作原理都相同。
二、刹车片多久更换一次
有人说刹车片更换看里程数,虽说有一定的根据,但并不准确,里程数仅仅作为一个参考,而根据驾驶人的驾车习惯与行车环境也有非常大的关系。
假如,新车的刹车按照原厂汽车使用说明,建议10万公里更换,但是你在实际的驾驶中,经常堵车,刹车使用频繁,你10万公里跑不到就需要更换,如果你经常跑高速,刹车使用频率不高,或许也会超过10万公里都不需要更换。到底怎么来看刹车是否需要更换呢?
1.通过控制刹车踏板的感觉
平时我们开车的时候,对于使用刹车一定有自己的感觉,也就是我们常说的“脚感”,包括油门也一样,所以对于刹车踏板使用的感觉也是非常敏感的。如果车在行驶过程中,同样的行驶速度,踩刹车要比平时感觉需要踩得更深的时候,也就是我们常说的刹车软硬的问题。或者,有明显的刹不住的感觉,这个时候我们就应该想到刹车是否需要更换的问题了,否则,很容易造成追尾事故的发生。
2.听刹车是否异响
汽车在高速运行中,当我们踩刹车的时候,刹车盘会跟刹车片摩擦,但我们平时几乎听不到刹车的时候会产生很尖锐的异响声。一旦出现异响,说明刹车片的磨损很大,刹车盘上与刹车片后面的金属物产生摩擦发出的尖锐的异响,这个时候,你也必须要及时检查更换刹车了。
还有一种,在更换过新的刹车片后,也会产生轻微的异响,不过,磨合几天以后,异响就会消失,如果一直有异响,说明刹车片有质量问题。
3.看刹车片的厚度
新刹车片的厚度为10mm,而磨损到极致的厚度为3mm,当低于5mm的时候,就该及时注意刹车,根据实际道路使用情况,提早更换。
4.仪表盘故障指示灯
现在很多车都有预警系统,刹车系统也不例外,在仪表盘中,有一个刹车盘指示灯,当此灯常亮的时候,说明刹车片磨损严重,需要及时更换了。
以上就是我们正确鉴别刹车片是否需要更换的标准,如果再通过里程数来衡量更换刹车时间,是不准确的。
三、网上购买的刹车片是否可靠?
随着电商的发展,很多人都喜欢从网上购买商品,包括汽车的配件,其实不管是汽配城还是网上商城,如果稍不注意,我们都会遇到副厂件,什么叫副厂件,其实就是所谓的高仿,虽然外观相同、但是价格相差很大,有的人为了贪图便宜,就会心动。
别小看一块刹车片,它的制造工艺和材料都是有讲究的,这也决定了刹车片的质量好坏与价格高低,刹车片的材料一般分为树脂基、粉末冶金、碳/碳复合、陶瓷,而陶瓷刹车片在所有的刹车片中价格最贵。
正所谓一份价格一分货,如果单从价格来区分,同样的刹车片价格低很多的,一定是副厂件。之前为了测试,专门从网上采购了一套刹车片,装了以后,后轮的刹车经常会发出异响,后来就直接换了原厂件,异响彻底消除,造成这样的原因,是因为刹车片的材料不好,与刹车盘摩擦产生的铁屑发出的声响。
如果网上价格低廉、刹车片异响则说明这样的刹车片不太可靠,购买的时候需要谨慎。
总结:刹车作为汽车常用的消耗件,车主应该了解它的作用及更换周期,提高行车安全系数,出行才能得到最大的保障。对于刹车的常识,你还有什么想说的吗?
