The frequency with which hydraulic brake systems require fluid replacement is a critical aspect of vehicle maintenance. It involves the complete removal of old fluid and its replacement with fresh fluid, ensuring optimal braking performance. An example is replacing the fluid every two to three years, or as specified by the vehicle manufacturer’s recommendation.
Regular fluid exchange offers significant advantages. Brake fluid is hygroscopic, meaning it absorbs moisture from the atmosphere. Over time, accumulated moisture lowers the fluid’s boiling point, potentially leading to brake fade during heavy braking situations. Maintaining fluid integrity improves braking responsiveness, enhances safety, and prolongs the life of brake system components. Historically, ignoring this maintenance item has resulted in compromised braking systems and increased risk of accidents.
