After driving in the rainy season or on waterlogged roads, some car owners may find that the vehicle has abnormal noises when the brakes are applied, which not only affects the driving experience, but also may indicate potential driving safety hazards. This article will deeply analyze the causes of the abnormal sound of the brakes after the car crosses the water from multiple perspectives, and give corresponding solutions to help car owners better maintain vehicle safety and ensure comfort and stability during driving.
1. The brake disc drum is corroded by moisture.
1.When the car wades through the water, the surface of the brake disc or brake drum is easy to absorb moisture, especially the impurities and salts in the rain, which is more likely to cause rust. When the rust rubs between the brake disc and the brake pads, it will produce a harsh abnormal sound, and in severe cases, it may also affect the braking effect.
2.Countermeasures: After wading in water, press the brakes appropriately several times in a safe section as much as possible, and use the friction between the brake pads and the brake disc to remove surface moisture and rust. In addition, regular maintenance of the brake system and keeping the brake disc dry and clean are key to preventing corrosion.
Second, the internal water ingress of the brake system.
1.When wading at depth, water may enter the brake fluid circuit or inside the brake drum through some gaps in the braking system. When water is mixed with brake fluid, it will reduce the boiling point of brake fluid, resulting in a decrease in brake performance and even abnormal brake noise.
2.Countermeasures: After wading in the water, go to a professional maintenance point as soon as possible to check whether the brake fluid is mixed with water, if necessary, the brake fluid should be replaced and the water inside the brake system should be removed. At the same time, it is necessary to pay attention to check the brake fluid level and the tightness of the brake system to avoid water infiltration.
3. Damaged or deformed brake parts.
1.During wading, sediment or other debris may wash into the inside of the brake system, causing scratches, deformation and other damage to the brake pads, brake discs or brake drums, resulting in abnormal noises during braking.
2.Countermeasures: After wading, a comprehensive inspection of the brake system should be carried out as soon as possible, including but not limited to the thickness of the brake pads, the surface condition of the brake disc, the internal state of the brake drum, etc., and if there is any abnormality, the damaged parts should be repaired or replaced in time.
Fourth, the brake booster system is affected.
1.In some models, the car's brake assist system may also be affected by wading. For example, vacuum booster pumps, electric booster systems, etc., if they are eroded by moisture, they may cause the brake assistance to weaken or even produce abnormal noise.
2.Countermeasures: After wading, check the brake booster system as soon as possible, especially the booster pump and related wiring, to ensure that there is no water infiltration. If a problem is found, it should be repaired or replaced by a professional technician.
The abnormal sound of the brakes after the car wades in the water is often the result of the brake system being affected by water erosion or other factors. When encountering such problems, car owners should attach great importance to them and take timely measures to eliminate hidden dangers to avoid affecting driving safety. At the same time, developing good vehicle maintenance habits and regularly inspecting and maintaining the braking system can effectively prevent the occurrence of such problems and ensure that the vehicle is always in a good and safe operating state.
