While replacing the brakes and rotors on my 300D today, I broke the retaining screw that holds the rotor to the hub housing. I fiqured it was okay to drive since the lugnuts go through the rotor and into the same housing. I plan on drilling out the broken screw and replacing ASAP. In the meantime, am I correct in assuming that the car is fine to drive?
