Virginia State Inspection Practice Test

Bonded or molded linings or disc pads are suspected to be worn when they measure less than what thickness?

1. 1/32 of an inch

2. 2/32 of an inch

3. 3/32 of an inch

4. 1/16 of an inch

The correct answer is: 2/32 of an inch

When evaluating bonded or molded linings or disc pads for wear, a thickness measurement of less than 2/32 of an inch indicates that they may be worn and require replacement. This thickness corresponds to approximately 1.5 millimeters, which is generally recognized as the minimum allowable thickness for effective braking performance. When linings or pads are worn below this thickness, the brake system's effectiveness can significantly diminish, leading to reduced stopping power and increased risk of brake failure. Keeping brake components within the specified thickness limits helps ensure vehicle safety and optimal performance on the road.
