Final answer:
Inserting a go/no-go gauge into the backing plate hole can determine the wear of the d0 brake shoe.
Step-by-step explanation:
When inserting a go/no-go gauge into the backing plate hole, the type of wear that can be determined is related to the brake shoe.
A go/no-go gauge is a precision tool used to check if the dimensions of a part are within an acceptable range. In this case, the gauge is used to measure the wear of the backing plate hole in a braking system.
If the gauge fits properly, it indicates that the brake shoe is within tolerance and does not need to be replaced. If the gauge does not fit, it means that the hole has worn beyond the acceptable limit and the brake shoe should be replaced.
