How to Operate the Brake Pedal After Driving Through Water
2 Answers
After driving through water, maintain low-speed operation and use the method of intermittently lightly pressing the brake pedal repeatedly to generate heat through friction between the brake drum and brake pads, thereby evaporating and draining the moisture. Pre-water measures before driving through water: 1. Unplug the motor wire connector, hang the wire ends at a higher position, and close the radiator shutter; 2. Wrap the distributor, high-voltage wires, and ignition coil with waterproof cloth or plastic bags, and raise the position of the battery; 3. Find a flexible hose to cover the end of the exhaust pipe and bend it upward above the water surface to prevent water from entering the exhaust pipe; 4. Wrap and block the fuel tank filler port, oil dipstick hole, and ventilation holes on the engine and drive axle with waterproof materials; 5. Increase the vehicle's weight as much as possible to reduce the buoyancy effect of water on the car and enhance wheel traction, ensuring stability while driving through water.
Last time I drove through a flooded area during a heavy rainstorm, I felt the brakes were spongy and it almost gave me a scare. Since then, I always lightly pump the brakes a few times after exiting the water to generate heat from the brake pads and evaporate the moisture. I've used this method several times, and the braking effect usually recovers within a few hundred meters. Never slam on the brakes in deep water—wheel skidding is minor, but water entering the brake system and causing rust is a serious issue. If the brakes still feel off after pumping them, get to a repair shop immediately to check the brake pads and hydraulic lines. Also, bearings are prone to sand intrusion after driving through water.
