刹车片什么时候需要换?通过细节来判断!

刹车系统是我们日常行车的保护神,如果出现故障的话开车出门是很容易出现突发事故的。那么,我们在日常的开车中怎么检查刹车片呢?正常行驶的情况下,前刹车片的寿命为2-4W公里,后刹车片的寿命为6-10W公里,所以,建议每3万公里检查一次前刹车片,每6万公里检查一次后刹车片。今天老司机就来告诉大家,怎样通过自己的检查来判断是否应该更换刹车片。

一、观察法

一个新的刹车片厚度(不包含刹车片钢铁背板的厚度)一般在10mm左右,当肉眼观察刹车片厚度已经仅剩原先的1/3厚度(约3mm)左右时,车主就要增加自检频率,随时准备更换了。通常在小于1mm左右厚度时就需要立刻更换,每个刹车片的两侧都有一个突起的标志,这个标志的厚度时在2—3mm左右,这也是刹车盘最薄更换的极限,如果刹车片厚度已经与标志平行,老司机提醒一定要马上更换。

二、听声音

如果在轻点刹车的同事伴随有“铁蹭铁”的丝丝声,此时刹车片建议立刻更换。因为刹车片两侧的极限标识已经直接摩擦车盘,证明刹车片已经超过极限。遇到这样的情况,在更换刹车片的同时要配合刹车盘的检查,出现这种声音时往往刹车盘已经受到损坏,此时即便更换新的刹车片仍然不能消除响声,严重时西药更换刹车盘。

三、感觉力度

当刹车片变薄时我们的刹车效果会受到影响,此时需要更深的踩下制动踏板才能达到原先轻踩就能达到的制动效果,前半程制动效果明显减弱。感觉自己的刹车变软,有点刹不住了,此时就要检车刹车片是否需要更换了。

此外,还有人在驾驶过程中,脚只有两个选择:加油,踩刹车。踩刹车的频率达到了很高的水平。事实上,这样的人并非少数。而这样做的结果,自然是2-3万公里,就得换一次刹车片。
