How to Solve the Water Sound When Braking a Car?

This situation is normal and does not require excessive handling. Water seeps in from the sealing strip outside the door glass, so there are 2-3 drainage holes at the bottom of each door, and the water will flow out from here. If the brake disc gets wet, it can be resolved through the car's automatic brake disc cleaning function. The automatic water removal function of the brake disc plays a certain role in the safety of the car.

Hearing a water-like sound when braking, I've encountered this several times, and it's usually due to air entering the brake system. The squeaking noise comes from air bubbles compressing in the fluid lines. This needs immediate attention, as it can make the brakes feel spongy, especially risky at high speeds. First, check the brake fluid reservoir to see if the level is low—low levels might indicate a leak or air ingress. Second, if the fluid is dirty or contains moisture, it needs to be drained and replaced. I once tried bleeding the brakes myself but made a mess due to inexperience; later, a professional shop fixed it easily with the right tools. Always check the brake fluid during maintenance to prevent long-term exposure to high temperatures.
