Tractor Repair: Long 445 tractor brakes, safe bet, rivets

Question
How do I remove the brake band from the  Tractor casting?
I have the axle and housing removed, the pin on which it rotates is also removed. I seems as though I need to remove the pins from the end of the band, is this right?

Answer
Hi Robin.
I have found several manuals on the www, but without purchasing one i cant open it of course.
But it would be a safe bet that the end pin would have to be removed do you think that it is just corrosion that is holding it on ?
What do the pins actually do? or do you mean rivets?
can you send a good photo , it would help.
