It is common for drivers to think that fluids only need to be replaced when they are running low. While that might seem logical, some fluids in your vehicle, especially brake fluid and coolant, are designed to be replaced on a schedule even if the levels are fine. That is because these fluids can degrade over time, losing their ability to do their job effectively. Changing them on schedule is a critical part of maintaining your vehicle’s safety, reliability, and performance. Why Brake Fluid Needs to Be Replaced Brake fluid is a hydraulic fluid that transfers force from your brake pedal to the brake components at each wheel. It operates under high pressure and heat, especially during repeated braking or in emergency stops. Over time, brake fluid absorbs moisture from the air, a process known as hygroscopic absorption. Even in a sealed system, tiny amounts of moisture enter through hoses and seals. This water contamination lowers the boiling point of the fluid ... read more
