What should be done first when inspecting low brake fluid levels?

When inspecting low brake fluid levels, the best initial step is to check for leaks in the system. Low brake fluid can often indicate that there is a leak present within the brake system, which could lead to a loss of braking efficiency or failure if not addressed. Identifying and repairing any leaks ensures that the brake system is operating correctly and that fluid levels can be restored to the appropriate level without ongoing loss.

Inspecting disc brake pads for excessive wear, although important, should not be the first action taken in this scenario. While worn brake pads can contribute to decreased braking performance, they do not directly cause low fluid levels. The problem must be addressed at the source, which is most likely a leak or another issue in the hydraulic system before focusing on components like brake pads.

In summary, checking for leaks first not only helps pinpoint the root cause of the low fluid level, but it also ensures safety and effective functioning of the braking system. Once any leaks are fixed, then further inspections, like checking the condition of the brake pads, can be appropriately addressed.
