During inspection, how often should brake fluid be checked?

Brake fluid should be checked regularly as part of routine maintenance because it is a critical component of a vehicle's braking system. The condition and level of brake fluid can significantly impact the vehicle's braking performance. Over time, brake fluid can absorb moisture, which may lead to reduced effectiveness and potential brake failure. Regular inspection allows for early detection of issues such as leaks or contamination and ensures that the fluid remains at an optimal level for safe operation.

Furthermore, regular maintenance helps ensure that other components of the braking system are also functioning properly, contributing to overall vehicle safety. In contrast, only checking brake fluid when the brakes feel soft or if visible leaks are present may result in dangerous situations, as these signs can indicate underlying problems that require attention before they lead to brake failure. Checking once a year, regardless of condition, is also insufficient, as brake fluid can degrade and require replacement sooner than that based on driving conditions and vehicle usage.
