1、剎車時異響
1. Abnormal noise when braking
踩剎車時，剎車系統會發出尖銳刺耳的金屬摩擦聲。
When you step on the brake, the brake system will make a sharp metal friction sound.
這有可能是因為剎車片變薄、剎車片坑洼、剎車片中有異物或剎車盤生銹等導致，一般情況多踩幾腳剎車異響都會有緩解。
This may be caused by the thinning of the brake pads, the hollowing of the brake pads, the presence of foreign matters in the brake pads or the rust of the brake discs. Generally speaking, if you step on more feet, the abnormal noise will be relieved.
剎車踏板行程變長
Longer brake pedal travel
直白點可以理解成剎車變軟。
Straight white dots can be interpreted as brake softening.
剎車行程變長的原因主要是剎車系統中進入空氣、缺少剎車油、可能存在泄漏、剎車片磨損嚴重等。

The main reasons for the longer brake stroke are air entering the brake system, lack of brake oil, possible leakage, serious wear of brake pads, etc.
剎車跑偏
Brake deviation
剎車跑偏的現象不是很常見，主要體現在踩剎車時方向盤有明顯的向一側偏轉。
The phenomenon of brake deviation is not very common, mainly reflected in the obvious steering wheel deflection to one side when stepping on the brake.
導致這種現象的原因可能是剎車片偏磨、剎車分泵有問題等。
The causes of this phenomenon may be the eccentric wear of the brake pad and the problem of the brake cylinder.
剎車變硬
The brakes harden
很多卡友會碰到剎車變硬的問題，剎車變硬的原因主要有真空助力器故障導致剎車無助力、頻繁踩剎車后導致等造成。
Many card friends will encounter the problem of brake hardening. The main reasons for brake hardening are vacuum booster failure leading to brake without power, frequent brake stepping and so on.
踩剎車時反有不少卡友碰到過這種情況，在踩下剎車時剎車踏板有反彈頂腳的現象，這種現象多為剎車盤、剎車片表面不平、鋼圈變形等導致。
When you step on the brake, many card friends have encountered this situation. When you step on the brake, the brake pedal rebounds and kicks. This phenomenon is mostly caused by the uneven surface of the brake disc and brake pad, and the deformation of the steel ring.
