A picture would help bunches, but if there is no bolt head left, you may have to drill the center of the bolt out and use and E-Z out bit. If there is still enough of the bolt head to grab on to you could use the bolt extractor tool, pic below. These are designed for dealing with stripped bolt heads. Sears would have these as well as any other place that has an abundance of specialty tools.

Championblythe is referring to the Anchor pin that holds the wheel cyclinder in place as well as holding the two springs.
If the bolt has rounded try squaring it with a file or grinder so it will except a socket. The anchor pin has a thread that bolts to the brake flange you can try WD40 to soak it.
I have seen a neat little trick where the thread was heated then normal candlewax was put on the thread to help unbolt it.
Hope that helps :anim_25:

I suspect champion is talking about the anchor pin for the brake shoe hold down springs and mounts the the wheel cyls. to the backing plate. Have you tried to use a 1 in. 6 point deep well socket? If the corners aren't rounded off and the socket fits snug try to break it loose with a 1/2in. drive breakover bar, before you do this spray it good w/ WD-40. Hope this helps.Good luck.

The front drum brake setup uses the anchor pin bolt to fasten the wheel cylinder to the spindle and backing plate. It's the big bolt at 12 o'clock on the assembly. It's not a 1" bolt, it's 5/8" or so, but the hex head is 1".
(The rear wheel cylinders are fastened by two 1/4" bolts, that's what you guys are thinking of.)
Unless the hex is seriously rounded, a 1" 6 point impact socket usually works, along with a serious impact wrench or a LONG breaker bar. Use some penetrating oil.
If the hex is damage too much for the 6 point, strip everything else off and try a pipe wrench on the round part. Or drill a big hole in it and use EZ out tools.
Edit: I see big Bob sees it the same way I do and finished typing first.
