How often should brake fluid typically be replaced?

Brake fluid should typically be replaced every 2 years for several important reasons related to the safety and performance of a vehicle's braking system. Over time, brake fluid absorbs moisture from the environment, which can lead to a decrease in its boiling point. As the moisture content increases, the fluid can become compromised, leading to potential brake failure under high heat conditions, such as during heavy braking.

Moreover, old brake fluid can accumulate contaminants that affect its ability to perform effectively, which can reduce the overall efficacy of the braking system. By adhering to a 2-year replacement schedule, vehicle owners can ensure that the brake fluid remains in optimal condition, contributing to consistent braking performance and enhanced safety on the road.

While shorter intervals, such as every 6 months or every year, might seem prudent, they are generally considered excessive for most driving conditions, leading to unnecessary costs. On the other hand, a replacement interval of every 5 years may allow brake fluid to degrade to a point where it could potentially compromise safety. Hence, a 2-year interval is widely accepted as a reliable recommendation for most vehicles.
