Well I am installing my toe elminators, and after I removed the rotor I noticed this grand canyon of a crack of the hub w/teeth on it for the ABS.

First of all I have no idea of how that would happen, the other side is fine, any ideas? How much of a problem is this? I know the best solution would be to replace it, but is there anything else, for atleast a while (jb weld)?

Anyways here is the pic...

 

that thing rotates at high velocity, I seriously doubt JB Weld would help.
If I were you Id´ replace it before driving the car again. If that thing shatters at highway speed youre are in deep ****

 

what he said.....thats looks serious!

 

i don't think those driving behind ya would appreciate it either.....
