Why is there a sound after washing the car when braking?

[StMatteo]

The reason for the sound after washing the car when braking is that water enters the brake drum of the wheel during washing, and sand particles splash onto the brake pads with the water, causing abnormal noise when braking. Braking, also known as stopping, refers to the action of stopping or reducing the speed of moving motor vehicles and other transportation machinery. It is divided into drum brakes and disc brakes. The maintenance methods for brakes are: 1. Regularly check the thickness and wear of the brake pads, and whether they return freely; 2. Replace them in time when the wear reaches the limit to avoid reducing braking efficiency and affecting driving safety; 3. Replace with brake pads provided by the original manufacturer; 4. Use special tools to push back the brake caliper when replacing; 5. After replacement, step on the brake several times to eliminate the gap between the shoe and the brake disc.
