What is the rejection criterion for air disc brake lining thickness?

The rejection criterion for air disc brake lining thickness is established to ensure proper braking performance and safety. In this case, a lining thickness of less than 1/8 inch indicates that the brake pads have worn down significantly and could compromise the braking system's effectiveness.

When the brake lining wears down to this thickness, it can lead to several issues, such as reduced stopping power, increased stopping distances, and potential damage to the brake rotor. Maintaining sufficient lining thickness is crucial for ensuring that the brakes can operate reliably under various conditions.

Although the other thickness options represent varying degrees of wear, they do not align with the established rejection standard for air disc brakes. A lining thickness of less than 1/8 inch is the critical threshold that signals the need for replacement to maintain optimal brake function and safety on the road, reflecting industry best practices.
