Should Brake Fluid Be Replaced?
2 Answers
Brake fluid should be replaced. Brake fluid is a liquid used in the hydraulic braking system of a car. To ensure its effectiveness, brake fluid needs to be replaced regularly. Otherwise, prolonged failure to replace it can pose hidden dangers to driving, potentially leading to insufficient braking pressure or corrosion of the braking system. Key considerations for brake fluid usage include: 1. If gasoline, diesel engine oil, or windshield washer fluid accidentally mixes with the brake fluid, it can significantly impair braking performance, and immediate replacement is necessary; 2. For vehicles equipped with a brake fluid level warning device, always monitor whether the warning indicator light is flashing and whether the warning sensor is functioning properly. When the brake fluid is low, it should be replenished promptly.
After driving for so many years, I firmly believe that brake fluid must be replaced regularly. Unlike engine oil where changes are more noticeable, brake fluid is a lifeline for driving safety. Over time, brake fluid absorbs moisture from the air, causing its boiling point to plummet. Imagine during emergency braking when temperatures soar—water molecules turn into vapor bubbles, making the brake pedal feel spongy and drastically reducing braking power. This could easily lead to a rear-end collision on the highway. I checked the manual, and it usually recommends replacement every two years or around 40,000 kilometers. Don’t skip it—it’s not expensive (just a few hundred bucks) but ensures peace of mind for years. You can easily check moisture levels with a test pen. If deteriorated, it can corrode metal components like calipers or the ABS pump, leading to costly repairs (thousands of dollars). Safety is non-negotiable—don’t cut corners here. Have it professionally replaced to ensure thorough flushing. During maintenance, don’t forget a full inspection, including brake pads and rotors, to safeguard safety comprehensively.
