How to Adjust the Brakes of a Four-Wheel Electric Vehicle?
3 Answers
The method for adjusting the brakes of a four-wheel electric vehicle is: 1. If the brakes feel soft, bleed the air from the system; 2. Adjust the brake pad travel by removing the tire and using a screwdriver to adjust the gear on the wheel cylinder. The maintenance methods for brakes include: 1. High-temperature protection to prevent corrosion of the brake system; 2. Clean oil stains from the brake discs, brake drums, and brake pads to ensure good heat dissipation of the brake discs; 3. Regularly replace the brake fluid; 4. Periodically check the thickness of the brake pads or brake shoes. The functions of the clutch include: 1. Gradually increasing the driving force of the vehicle for a smooth start; 2. Temporarily separating the engine and transmission for gear shifting; 3. Preventing overload of the transmission system; 4. Reducing torsional vibration impacts from the engine and extending the lifespan of transmission gears.
That day, I was driving my four-wheel electric sedan home when I noticed the brakes felt spongy, and the car would slide several extra meters before coming to a stop. Adjusting it myself wasn’t actually difficult: lift the seat or remove the chassis cover to locate the adjustment nut connected to the brake cable. A regular household wrench will do the job—turn the nut counterclockwise to tighten the brake cable or clockwise to loosen it. After each quarter-turn adjustment, take the car for a test drive and check if the wheels lock up during hard braking without skidding. This method works best for mechanical brake models, but remember to wear gloves to avoid scraping your hands. After the adjustment, the brake responsiveness improved immediately, making rainy-day driving much safer. If the brakes still feel soft after adjusting the nut, it might be due to worn brake pads needing replacement—if you can’t handle it yourself, take it to a repair shop.
As someone who frequently deals with electric vehicles, let me explain how to adjust the brakes. Electric vehicles have two types of brakes: mechanical cable type and hydraulic disc brakes. The former only requires adjusting the cable nut, while the latter requires changing the brake fluid. If you're adjusting it yourself, focus on the cable type—first, ensure the brake pad thickness is greater than 3 millimeters. With the vehicle stationary, press the brake and listen for any abnormal friction noises. The adjustment point is usually in the middle section of the frame. Use a 14mm wrench to slowly turn the adjustment nut: turning toward the front of the vehicle tightens it, while turning toward the rear loosens it. The key is not to adjust it too tight, otherwise the wheels won't turn and it will consume more power. After adjusting, test it by braking sharply at 20 km/h—if the stopping distance is within 3 meters, it's acceptable. Remember to adjust it once before the rainy season each year to prevent brake slippage.
