What type of maintenance is performed during a brake inspection?

During a brake inspection, the primary focus is on the components that directly affect the braking system's performance and safety. This includes checking the brake pad thickness to ensure they have enough material left to function effectively and inspecting the condition of the brake rotors, which are critical for safe and efficient braking. Worn or damaged pads or rotors can significantly impact stopping power and could lead to safety hazards.

In contrast, while checking tire pressure, inspecting oil levels, and replacing windshield wipers are all important maintenance tasks for vehicle upkeep, they do not pertain specifically to brake performance or safety. Tire pressure affects handling and ride comfort, oil levels are vital for engine health, and windshield wipers are necessary for visibility but are unrelated to the braking system's condition. Thus, checking pad thickness and rotor condition is essential for ensuring the integrity and effectiveness of the brakes.
