Can I Still Drive My BMW When the Brake Fluid Maintenance is Due?
2 Answers
You can still drive your BMW when the brake fluid maintenance is due, but you should promptly visit a repair shop or 4S store for replacement. Here are the characteristics of high-quality brake fluid: 1. Excellent rust prevention for various metals in the braking system: Generally, brake fluid is highly corrosive, but high-quality brake fluid significantly reduces corrosion and rusting on various metals, extending the lifespan of the brake oil pump. If inferior brake fluid is used, it will quickly corrode the metal, posing a hazard to driving. 2. Excellent low-temperature fluidity: This is particularly noticeable in extremely cold regions. High-quality brake fluid ensures the brakes remain sensitive and reliable even in severe cold. Inferior brake fluid performs poorly at low temperatures, with a high freezing point, and may solidify at temperatures below -20°C, greatly compromising driving safety.
Last time when my BMW's brake fluid expired, I firmly chose not to drive because brake fluid absorbs moisture, which lowers its boiling point and may cause brake failure under high temperatures, potentially leading to accidents in severe cases. BMW's braking system is precisely designed, and even a minor issue can amplify risks. I usually make it a habit to check the brake fluid level and color on time. If it appears cloudy or shows signs of moisture, I send it for repair immediately. The brake fluid maintenance cycle is typically every two years, and I set a phone reminder in advance to avoid forgetting. I remember once delaying it, and the brakes became soft, nearly causing a rear-end collision—a profound lesson. Now, safety is my priority, so I directly tow the car to a professional shop for a fluid replacement. Maintaining a vehicle is a responsibility, and procrastination only increases repair costs and risks.
