"blistering hot is about 140F" this is normal for brakes that are used.
Too hot drums = overheat and heatscore them and all the brake components inside. Ive seen heatscored brake shoes and its not pretty, they usually crack from the heat.
The "Shoe-to-drum clearance" is 0.6mm if this was a 2005 Corolla.
However, since you are an expert in metallurgy, you should at least know what type and year car in order to get the correct brake procedure.
In your prior post, your sister's car was a 2008 Hyundai and you "dont botehr with her anymore".

Poor car is gonna get taken to the cleaners in the next 9 years. Its darkest days are ahead of him. If its even gonna last that long, cause its Hyundai."
