What should a driver do if they notice a spongy brake pedal?

Answer: B — Check for brake fluid issues

When a driver notices a spongy brake pedal, it indicates that there may be an issue with the brake system, typically related to the brake fluid. A spongy feeling often results from air trapped in the brake lines or low brake fluid levels, which can lead to reduced braking effectiveness and potentially cause a complete brake failure if not addressed. Checking for brake fluid issues is a crucial first step. This includes inspecting the brake fluid level in the reservoir and looking for any leaks in the brake lines or connections. If the brake fluid is low, it may need to be topped off, or there might be a more significant problem that needs professional attention. Ensuring that the braking system is functioning properly is vital for the safety of the driver, passengers, and others on the road.
