Why does the electronic brake vacuum pump make noise when braking?

Electronic brake vacuum pump makes noise when braking because electric vehicles lack an engine, reducing the vacuum source originally provided by the engine intake manifold, necessitating the addition of an electric vacuum pump. Here are some extended details: 1. Function: It mainly extracts air from the vacuum booster in the braking system to enable the booster to provide actual assistance. Therefore, braking consumes the vacuum source inside the vacuum booster. 2. Reduced vacuum level: When the vacuum pressure sensor detects a decrease in the vacuum level inside the booster, it activates the vacuum pump, causing it to work and produce noise. Each brake application consumes vacuum, so every time the brake is pressed, the vacuum pump operates.

How to Deal with Water Leakage in a Car Sunroof?

To address water leakage in a car sunroof, follow these steps: 1. Inspect the rubber seal and grooves of the sunroof for dirt such as sand, leaves, or small branches; 2. When using a high-pressure water gun to wash the car, avoid directly spraying water at the sealing ring around the sunroof, as this can cause the seal to deform under the high-pressure water stream, leading to potential water leakage over time; 3. Regularly check the sunroof sealing ring for signs of aging. During spring and autumn, clean the sealing ring with a damp sponge every season. Before long-term parking, thoroughly clean the sunroof with talcum powder to prevent the rubber seal from undergoing chemical changes and natural aging due to prolonged exposure to air.
