When you buy new rotors... do you use the already installed races (if the rotor actually has them)... or do you use the races that came with your new wheel bearings? Just curious.

Also... is the long grease gun type tube here the same as the short 'wheel bearing' one pictured below? I have the long tube one, as I could not fin the other one locally.
