what do you need for a front brake job?

When you put the drums back on, either originals turned or replacements, tighten the castle nut by hand until there's drag on the bearings then back it off until it lines up with an opening (notch) to get the cotter pin in. If it's tight where it's lined up with a notch back it off a full notch. You don't want drag (tightness) on the front bearings.
