What should an inspection mechanic do if bonded brakes measure 3/32?

When bonded brakes measure 3/32 inches, this measurement indicates that the brake lining is nearing the minimum thickness required for safe operation. The correct action is to pass the brakes but inform the owner in writing. This helps ensure that the vehicle owner is aware of the brake condition and the potential need for future maintenance or replacement without immediately failing the inspection. This written notice serves to document the condition of the brakes for the owner, emphasizing the importance of monitoring brake wear and considering replacement in the near future to maintain safety and performance.

The other choices do not align with standard inspection procedures. Simply passing the brakes without any notice disregards the duty to inform the owner about the potential safety implications. Failing the brakes and requiring immediate replacement would be excessive since 3/32 is not below the legal limit for bonded brakes. Advising the owner to make further modifications is vague and not a standard inspection action; rather, it is better to be direct about the existing condition and communicate the necessary steps for maintenance.
