Brakes Making Noise? Squeaking and Grinding Explained

Brake noises are your car's way of telling you something is wrong. Squeaking usually means something different from grinding — here's what each noise means and how urgent the fix is.

Brakes Making Noise? Squeaking and Grinding Explained

刹车声音是最常被忽视的警告信号之一。有些车主习惯了噪音就不再在意——但每种声音都有其含义。

吱吱声(高音摩擦声)

**刹车时才有吱吱声**:最可能是刹车片磨损警示条(金属片)接触刹车盘发出的提醒——该换刹车片了。

**停车或低速行驶时有吱吱声(不踩刹车)**:可能是刹车盘表面轻微锈蚀(停放一晚后常见),通常开几脚刹车后会消失,属于正常。

**所有速度都有吱吱声**:刹车盘变形或卡钳卡住,需要检查。

磨磨声/磨削声(低沉金属刮擦声)

**踩刹车时明显的磨削声**:刹车片已磨光,金属底板直接接触刹车盘——非常严重,立刻停止驾驶或尽快去修车。

继续开车会在短时间内损坏刹车盘(价格是刹车片的 3–5 倍),同时制动力也在快速下降。

咯咯声/松动感

踩刹车时有咯咯声、或刹车踏板感觉松动:刹车卡钳支架螺丝松脱,或刹车片没有固定好。

这种情况比较罕见但较危险——卡钳松动会导致刹车力不稳定。

刹车踩下去踏板抖动

不是声音问题但相关:踩刹车时方向盘或踏板有明显振动,通常是刹车盘变形(Warped Disc)。

高速行驶后突然急刹、或长时间下坡频繁刹车都会导致刹车盘局部过热变形。

需要打磨或更换刹车盘。

该多紧急处理?

吱吱警示声 → 安排换刹车片,不用立刻,但不要再拖超过 1–2 周。

磨削声 → 尽快,最好当天处理,不要再长途行驶。

踏板松软或几乎踩到底 → 禁止驾驶,检查刹车液是否大量泄漏。
