Why does the car make a squeaking noise after passing through a puddle?

[MacIsabelle]

If your car makes a squeaking noise after passing through a puddle, it might be due to an issue with the chassis. Here is some information about the car chassis: 1. Introduction: The chassis refers to the combination of the transmission system, running gear, steering system, and braking system in a car. 2. Function: It supports and installs the car engine and its various components and assemblies, forming the overall shape of the car, bearing the engine's power, and ensuring normal operation. 3. Running gear: The leaf spring's role is to maintain an elastic connection between the frame and the body with the wheels or axle. The shock absorber's function is to mitigate vibrations when the car is subjected to shock impacts. The shock absorber is used in parallel with the leaf spring.

My car often makes a squeaking noise after going through puddles, which is quite annoying! Actually, most of the time it's just noise caused by wet brake pads. Water splashed from the puddle hits the brake discs, and this sound occurs when the pads rub against the discs. It usually disappears on its own after driving for a few minutes as the water dries up. If the noise persists after driving for a while, it might be because the brake pads are too thin or there's sand stuck in them, so it's best to get them checked. This is common during the rainy season, and I usually lightly press the brakes a few times afterward to speed up water drainage. There's no need to worry too much—it's just like the squeaking sound shoes make when walking through water, a minor everyday occurrence. However, it's important to stay alert and ensure it doesn't affect safe driving, just in case.

After years of researching cars, I've found that squeaking noises are commonly a temporary phenomenon when water enters the brake system. The principle is that water lubricates the friction surfaces, altering the frequency of sound wave vibrations. When driving through puddles, water impacts the wheel hubs and splashes into brake components like calipers or between discs, causing that noise. It naturally disappears once the water evaporates or friction generates heat, which is normal. If the noise persists for several kilometers or more, consider issues like excessive brake pad wear, oxidation, or foreign objects, requiring cleaning or replacement. Frequent exposure to water during the rainy season accelerates wear, making regular thickness checks crucial. I recommend a monthly visual inspection or a professional check. Other components, such as belts getting wet, might also squeak, though this is less common.

I've been driving for decades and encountered similar situations countless times. The squeaking noise after going through a puddle is most likely caused by wet brakes, where water adheres to the metal surface and creates friction sounds, much like a spatula scraping a pot. It usually stops within minutes as the water dries, requiring no repair. This happens more frequently during rainy weather. For safety, I drive slowly to let the discs heat up and evaporate the moisture faster. If the noise persists long-term, it's time to check the brake pads' lifespan and replace them if they're too thin. This is a minor issue that routine maintenance can handle—no need to waste money on urgent repairs unless accompanied by shaking or unusual odors, which indicate real problems. Experience tells me most cases can be safely ignored.
