Start out by stripping off all of your old drum brake stuff. That’s right—down to the spindle. Now that you have the hub and drum off you should find someone who can press the old wheel studs out or you can bang them out with a hammer. Next, place the rotor behind the hub and have the wheel studs pressed through the rotor and into the hub. If you don’t put the rotor behind the hub your brakes won’t line up with the calipers.
