    Allen Bolt holding the Rotor

    I destroyed the allen bolt holding both the front rotor and thread is gone for both (had to drill them both as PB Blaster is no match even soaking them overnight).

    My question is it okay to disregard the allen bolt and use the caliper to just hold the new rotor in place or do I need to purchase the wheel hub?

    thanks for any input.

      Correct me if I am wrong, but I believe the allen bolt is only for holding the rotor in place while you mount your wheel. The lugs should hold things in place, but it will be a huge PITA to mount your wheels unless you have studs.

        the brake caliper and pads will hold it in place pretty well.

            It could be....
            What I do is use the wheel mounting tool in our tool tray on the first lug. Then after that, it's gravy. Just don't hit the put on the ebrake, it will move the hat and mis-align it with the hub.

              You have an e-brake on your front wheel? Baller! :p

                Rear, and as far as I am concerned, your fiddle would make an excellent wheel chock in a pinch.;)

                  You know, you can say what you want about me and my car but my violin is worth more then most of the cars on this board. Combined. It is an exquisite instrument of 1940's german craftsmanship and has nothing to do with me personally except that I play it. You want to make fun of my music, fine. You want to make fun of my car? Even better. Leave the instrument out of it, dickwad.

                    And just so we're clear, the OP asked about his front hub and you brought up the ebrake...

                      it's not a big deal to use the rotor set screw if you use anti seize and don't he-man the things on there. finger tight is plenty, but for some reason I imagine people getting out their breaker bars and torquing them down until they almost pass out. Never had a problem getting one back out and have even been able to reuse a few.

                        Same thing happened to me, like everyone else said you'll be fine without them. I've driven about 5,000 miles without them and had no problems.

                          I believe he was simply joking. Calm down. As a musician, you should be used to the riff-raff making fun of us as an attempt to make it seem like they are somehow better than musicians.

                            Thanks to all for the feedback.

                            Also, I just got this car and those allen bolts are like not been removed since...

                            Looking at the rotors, they probably just keep on changing the pads without changing the rotors? pads are ok but rotors are really warped out, grooves are really deep and never seen so much rust in a rotor.

                            I'll be doing the rears, so what are other anti-seize products other than PB Blaster before I use my drill again? TIA

                              impact drivers work excellent. if they're that bad you may have to use some heat. the only reason the screws are there are to keep the rotors from falling off while the car goes through the assembly line.
