Because of the strong adsorption of the braking system, rainwater can easily enter the brake fluid, which affects the braking effect and even fails. Once the brake fails, it will pose a serious threat to safety, so check the brake system after the rain.

2. Skylight inspection

For the whole vehicle, the skylight is a weak place. Check whether the rubber strip of the skylight sealing ring is intact after the rain. If the window is cracked or incomplete, rain can easily penetrate into the car. In addition, the skylight guide rail should be lubricated.
