Them's tha Brakes?
I have a 66 F100 with drum brakes. I tried to check the brake shoes the other day, and couldn't get the front drum off. The back was easy enough, for a rusty drum, but both fronts act like they are frozen. One even has a chunk broken out of it were it looks like the PO tried to hammer them off.
So how do the front drums come off?

Not to demean your knowledge but did you take the center cap off of the spindle and remove the wheel bearings? if not then thats your problem. other than that they may be completely worn out and dug into the drum, so you might need to with a brake toool adjust the pads in so that the drum will clear them.

Thanks! and you're not demeaning my knowledge at all, I have none. 
Thats what I did wrong, I was treating them like the rear drums, and just trying to pull them off.
Any Idea what size nut that is? I'll have to pick up a socket for it on the drive home.

A cresant wrench is what I always use. be sure to take the cotter pin out of it before tryin to loosen it. once the pin is out you will probably be able to take the nut off with your fingers. while you have them apart it might not be a bad idea to replace the wheel bearings for good measure. be sure to clean everything really good in a solvent preferably and regrease with as much grease as you can smash in there with your fingers. good luck. but you shouldnt need a socket to do it, unless you just really want a new socket. haha.

Yes there is such thing as to much grease.. I deal with this all of the time at work. We have shaft bearings as large as 6" shaft size and when they are over greased I have seen the temperature rise as high as 250 + degrees F. They normaly run about 125 degrees F running at 1200 RPM. When this happens we have to re-pack the bearings with fresh grease due to the break down in the grease once it is overheated. Most grease fails at about 210 degrees F.
Just make sure you purge fresh grease all the way through the CLEAN bearing and coat the rollers with a thin layer, also add a thin layer to the CLEAN race. This should be plenty. There is also a small groove besides the race that can be filled level with grease. Do not fill the center of the hub with grease this is kind of an overflow area. I have been using this technique since it was taught to me by father who has been doing it that way since the 1940's without a failuer.
