How to Replace Brake Fluid for Electric Vehicles by Yourself?
2 Answers
Electric vehicle brake fluid can be replaced by yourself using the following method: 1. Open the brake fluid reservoir cap and slightly loosen the bleed screw on the caliper; 2. Allow the cloudy brake fluid to drain out through the bleed hole, then add new brake fluid into the reservoir until clean fluid is observed, and finally tighten the bleed screw. An electric vehicle, also known as an electric drive vehicle, is powered by electricity. Electric vehicles are categorized into AC electric vehicles and DC electric vehicles. Typically, electric vehicles use batteries as their energy source, converting electrical energy into mechanical motion through components such as controllers and motors, with speed adjusted by controlling the current.
Replacing the brake fluid of an electric vehicle by yourself is quite similar to that of a conventional car. Let me guide you through the process step by step. You'll need new DOT4 brake fluid and tools like an open-end wrench and a fluid extractor. Locate the brake fluid reservoir, usually near the engine compartment. Use the wrench to loosen the reservoir cap and extract the old fluid with the tool, being careful not to drip it on the car paint as brake fluid can corrode surfaces. Then, slowly pour in the new fluid, but don't overfill it—leave some space to avoid overflow. The crucial step is bleeding the brakes: have someone press the brake pedal inside the car while you gradually loosen the bleed screw near the wheel to release air, then tighten it back. The whole process takes about an hour—remember to wear gloves and safety goggles for protection. Brake fluid should be replaced every two years, as prolonged use leads to moisture absorption, which can impair braking performance. This is especially important for electric vehicles, which accelerate quickly and rely heavily on their braking systems. Regularly check the fluid level and ensure it remains clear and transparent. Doing it yourself can save you hundreds in labor costs.
