Brake rotor source?

I got the Brembos from Motobins. They look exactly like the originals.

Presumably they don't crack like the original disks sometimes did.

A side story: I had a cracked disc and I wondered how easy it would be to make the cracks worse. As an experiment I tried several things, including whacking the disc smartly with a hammer. The cracks remained the same. Then taking sterner measures I would heat one side of the crack red hot with my oxy acetylene torch and then plunge the disc into cold water. I thought that surely the differential temperatures on each side of the crack would cause it to elongate. But it didn't. I finally ran out of ways to 'insult' that disc and it remained just the same. No more cracking. In a way I was kind of disappointed.

To be clear, I would never even think of using a cracked disc. But I have no problem beating up one.

The very definition of a crack addict...IMO

The original rotors are scored, but functional. No cracking. I think the scoring is from using aftermarket brake pads that probably had more aggressive metal content. But I don't know this for sure. The folks at Motobins felt that the Ferrodos pads were easier on the rotors than even the stock pads. It will be interesting to see how the brakes perform with new rotors, pads, and I will re-build the calipers as well. I installed steel braided lines twenty five years ago. I wonder if they should be re-used. I guess I should rebuild the master, but it was replaced at one point. Can't be too conservative with brake safety
