What is the correct procedure for checking brake pads?

The procedure for checking brake pads involves inspecting for wear and ensuring they have the proper thickness. This is critical because brake pads are essential components of a vehicle's braking system, and their effectiveness is directly related to their thickness. Over time, brake pads wear down due to the friction generated during braking, and if they become too thin, they can lose their ability to provide adequate stopping power. Regularly checking the thickness helps ensure safe operation and timely replacement, preventing potential brake failure.

While assessing other components related to the braking system, such as checking for rust, loose screws, or brake fluid levels, is important for overall vehicle maintenance, these actions do not directly address the condition of the brake pads themselves. Therefore, focusing on the wear and thickness of the brake pads is the most pertinent procedure during a pre-trip inspection.
