The act of evacuating air bubbles and contaminated fluid from hydraulic braking systems on bicycles is a maintenance procedure crucial for optimal performance. This process ensures that the brake levers provide firm and consistent stopping power. For example, when spongy or unresponsive brakes are experienced, it often signals a need to perform this procedure.
Maintaining a properly bled braking system is essential for rider safety, ensuring reliable deceleration and preventing brake fade, especially during prolonged descents. Historically, neglecting this aspect of bicycle maintenance could result in compromised braking effectiveness and potentially dangerous situations. The evolution of hydraulic braking systems has necessitated the development of specific techniques and tools for this maintenance task.
