How frequently should brake fluid be replaced?

Brake fluid should typically be replaced every two years or as specified in the owner’s manual due to its tendency to absorb moisture over time. Moisture in the brake fluid can lower its boiling point, which could lead to reduced braking performance and potential failure under heavy braking conditions. Regular replacement ensures that the brake fluid maintains its hydraulic properties and efficiency. Moreover, vehicle manufacturers provide specific intervals in the owner’s manual based on the vehicle's design and the type of brake fluid used, which gives drivers tailored guidance for optimal maintenance. Following these recommendations helps ensure the safety and reliability of the braking system.
