There is a tool for that job, I will probably need to buy one too. This is from the DJS tractor parts catalog, but they are available from just about anywhere that deals in allis stuff

| If you’ve messed up the end of the pin, the tool probably wont help. You could get an all-thread coupler (a nut thats about 3-4 times longer than a standard nut) and weld it to the outside end of brake pin and use a slide hammer (if there’s room) or thread some all-thread into it, then slide a large deep well socket over the all-thread and some washers and a nut. Crank down on the nut to pull pin out. Probably heat the pin again first…. |

| touch out from the bottom...keep driving pin in as cut out. The pin is usually stuck at the outer location meaning the inside piece can be removed more easily |

Those tools have about a 25% success rate, rest of the time they just pull the head off the pin. I have cut the pins out on a couple but a better approach is to drill and tap them and fashion a puller out of a short length of pipe or something. Pins will still be usable afterword. Think I tapped them 1/2-20. |

| After you pull off the top of the pin, seriously weld a 5/*" nut inside the hole to the pin really burning it in with lots of heat. Let cool cold. Gently use a 1/2" impact wrench to get it to rotate and then it will come out. |

You can use a bolt For the bottom pin. Use a grinder to notch it.
