What should be checked in the braking system before adding brake fluid?

Before adding brake fluid, it is essential to check for leaks and the wear of the brake pads. This step is crucial because if there are leaks in the brake lines, adding fluid could mask an underlying problem, leading to loss of braking power and potential safety hazards. Additionally, worn brake pads may indicate that the braking system is not functioning optimally. If the pads are severely worn, simply adding fluid won't resolve the issue and could lead to brake failure.

By identifying leaks and assessing the condition of the brake pads, you can ensure that the braking system is in proper working order and that it is safe to drive. This proactive approach helps maintain the vehicle's braking efficiency and overall safety.
