2012 Camry do you need to replace Rotor bolts
 

On a 2012 SE 4 cylinder Camry. when replacing the rotors, do you need to replace the bolts that hold the mounting bracket that they sit in? I know that there are some car companies that use stretched bolts in the brake parts and I am not sure if Toyota does or if it makes a big difference?

No.

For stretch bolts, the shank is typically a smaller diameter then the threaded end to allow stretching.

Thank you very much.
