After driving through floodwaters or after washing your car, water may leak into the brake system. Humidity or water can cause the brake system to malfunction or cut off, reducing the efficiency of the brake system, especially the brake fluid, which may deteriorate. And moisture that comes into contact with the brake metal for a long time may cause rust.
Recommendation: After driving through floodwaters or after washing the car, the driver should test the condition by gently stepping on the brakes several times to remove moisture from the brake pads and brake discs. For manual transmission cars, the driver should also press the clutch pedal to prevent the clutch from slipping due to moisture.
To remove moisture from various systems after driving through flooded water, before turning off the engine, run it gently to remove moisture from various systems to prevent the engine from stalling or having electrical problems when driving again. Or, leave the engine without turning it off for about 20 minutes with the air conditioner on. This will help the engine dry out faster. However, after driving through flooded water, you should immediately take care of and clean it because if you leave it for a long time, it may cause the car to have accumulated problems that may be difficult to fix later.

Using faulty brake pads while on a long trip increases the risk of an accident. Check for signs that it's time to replace your brake pads so you can monitor and prepare for your journey.
