As you ground out the crack line there may have been enough clean metal revealed to, just, take the braze metal.

If it is ceramic coated then you really may not be able to trust the integrity of that braze though.

I didn't know that about ceramics being applied. That makes some sense cause when I heated it with the torch it just popped off and the braze did not tin to the surface but the vee I ground it did tin too although not too easily. It is a crappy looking braze but will hold and should not leak too bad.
