my repop brake shoe pins........
 

.......are too soft. the pins for rollers are the ones in question. i have many originals, but they are all worn. but they are hard, can't touch them with a file. the repops i have are unused and i have had them for years. they can be easily filed. are the current ones available the same or harder? these would last for awhile, but i don't want to use them any information appreciatted.
