制动警告、磨铁声或刹车变软：安全停车处理
Brake hydraulic and friction-system repairs are not beginner DIY work. This guide explains when to stop and what to report.
制动液压与摩擦系统不属于入门 DIY；本帖只说明何时停车以及如何描述问题。

1. Recognise the danger signs
A red brake warning while driving, pedal sinking to the floor, pulling strongly, grinding, fluid leakage or greatly increased stopping distance requires immediate action.
识别危险信号
行驶中红色制动警告灯亮、踏板沉到底、车辆严重跑偏、磨铁声、制动液泄漏或制动距离明显增加，都需要立即处理。
2. Stop without creating more risk
Ease off the accelerator, switch on hazards, keep a large gap and move to a safe place. Use gentle progressive braking; do not pump or apply the parking brake abruptly at speed.
安全停车
松开油门、打开双闪、增大车距并移至安全位置；平稳逐步制动，高速时不要猛拉手刹或随意反复踩踏。
3. Do not top up and continue
Low brake fluid can indicate worn pads or a leak. Adding fluid does not repair the cause and may hide evidence.
不要补液后继续开
制动液低可能表示刹车片磨损或系统泄漏；单纯补液不能修复原因，还会掩盖故障证据。
4. Tow for inspection
Do not drive again. Tell the workshop when the symptom began, which warning appeared, pedal feel, noises and whether fluid is visible.
拖车检查
不要再次驾驶；向维修店说明故障开始时间、警告灯、踏板感觉、声音以及是否看到液体。
