How can customers ensure their brakes are functioning properly?

Customers can ensure their brakes are functioning properly by listening for unusual noises and checking brake fluid levels. Unusual noises, such as squeaking or grinding sounds, can indicate potential issues with the brake pads or rotors. When brake pads wear down, they can produce these sounds as a warning sign that they need to be replaced. Additionally, monitoring brake fluid levels is crucial because low brake fluid can lead to reduced braking efficiency and a risk of brake failure. Proper maintenance of the brake system, including regular checks for fluid levels and auditory signs of wear, helps maintain the overall safety and functionality of the vehicle.

Other options do not directly contribute to ensuring brake functionality. Tire pressure checks are important for overall vehicle safety and handling but are not specific to brake performance. Oil changes play a critical role in engine health rather than brake systems. Headlight inspections are essential for visibility while driving but do not provide any direct information about brake condition.
