Has anyone seen a rotor break like this before?

First one for me. Did that fall apart from applying brakes or did they hit a curb?

Maybe they used a crow bar trying to remove a wheel?

I dont think they hit anything. Everything else looked good. Ticket said "brakes broke" and well, yeah its broke alright. No tellin what they did they have always brought it to the dealer for service. Like Tom said must be that damn ol' chinese tin that they call steel.

Just weld it up and turn it down - good as before...

ive seen this before.did the shim on the brake pad get loose and cut through the rotor?I had it happen on an astro van.
