Thanks Peter.

The MB service manual states that the hex bolts are not to be reused and ordered new ones. Looks like they have a coating of Blue Loctite on them. Guess the removed ones can be used again if a coating of Loctite is applied. I didn't order new caliper bolts, but will use Loctite upon installation.

The service manual states to remove the rotor by placing 3 M12X1.5 bolts in the hub and placing it in a vice. Guess the boltse used to protect the hub while crimping.

Thanks again,

Gympie
