What are your options if a rotor has a discard of 24.5 mm and a minimum refinish specification of 25.3 mm, and currently measures 24.76mm?

When you evaluate the measurement of the rotor, which is currently at 24.76 mm, it is essential to consider both the discard threshold of 24.5 mm and the minimum refinish specification of 25.3 mm. According to the standards, if a rotor measures less than the discard value, it should be discarded, and if it can't be refinished to at least the minimum specification, it cannot be reused safely.

In this case, the rotor’s current thickness of 24.76 mm is above the discard limit of 24.5 mm, meaning it is still structurally sound enough to consider for reuse. However, the rotor must also be judged against the minimum refinish specification of 25.3 mm, which is critical for safety and performance.

Option C states that the rotor can be reused without being machined, which is appropriate because the rotor, at 24.76 mm, is above the discard limit and is within the realm of acceptable thickness to be put back into service as is. It’s permissible to use the rotor without machining since it is over the discard threshold and does not yet fall below the minimum refinish specification when accounting for a potential machining process.

This approach ensures that the component is safe and
