What Causes the Sound of Water Sloshing Behind the Brakes?
2 Answers
Brake behind the water sound may be caused by the rear seat or the nearby sound insulation cotton not being properly covered. Here is some information about brakes: 1. Introduction: It is a mechanical braking device that can slow down the speed of a vehicle, also known as a decelerator. 2. Operating Principle: The car brake pedal is located under the steering wheel. Pressing the brake pedal causes the brake lever linkage to be pressurized and transmitted to the brake shoes on the brake drum, which then clamp the brake disc, slowing down or stopping the vehicle. 3. Operating State: The manual brake of a car is located next to the gear shift and is connected to the brake lever. Another common type is the bicycle brake, which relies on rod-shaped brakes fixed to the frame or disc caliper brakes to slow down the bicycle.
I previously noticed a sloshing sound from the rear when braking, and after some troubleshooting, I discovered the door drain holes were clogged. After rain, water couldn’t drain and accumulated in the door cavity, making a splashing sound when braking. Also, the drainage channels on both sides of the trunk tend to collect leaves and mud, holding several pounds of water. A mechanic taught me to use a thin wire to clear the drain holes, and now I check them every time I wash the car. By the way, some cars have drainage holes under the spare tire well—if these get blocked, even the trunk mat can get soaked, so pay extra attention.
