How Far Can You Drive with Insufficient Brake Fluid?
2 Answers
Driving with insufficient brake fluid is not recommended. Here are the relevant details: 1. Hazards: When brake fluid is low, it is advised not to continue driving as air can enter the brake lines or wheel cylinders. Since air is compressible, it can lead to insufficient pressure in the wheel cylinders, resulting in reduced braking performance or failure. 2. Precautions: If gasoline, diesel, engine oil, or windshield washer fluid accidentally mixes with the brake fluid, it can significantly impair braking effectiveness. Immediate replacement is necessary. Under normal driving conditions, brake fluid should be replaced every 40,000 kilometers or every 2 years, whichever comes first, as prolonged use can cause the fluid to deteriorate. Therefore, timely replacement is crucial.
My heart skipped a beat when I saw the brake fluid warning light come on – this is no joking matter. Last winter during a long-distance drive, I encountered this exact situation with 15 kilometers left to the next service area. Although I gritted my teeth and crawled at a snail's pace of 40 km/h to reach my destination, the brake pedal felt as soft as stepping on cotton the entire way. The scariest moment was when I had to make an emergency maneuver and almost rear-ended another vehicle. Brake fluid is responsible for transmitting hydraulic pressure in the braking system. When it falls below the minimum level, the pump can draw in air, creating vapor lock. My advice: if you see the brake fluid warning light, pull over immediately and call for roadside assistance to arrange a tow truck – that's the correct procedure. Never gamble on how far you can push it.
