1986 Fourtrax 250 brakes

New to the site, did some quick looking around and didn't see the answer. Quite possible I missed it. The brakes are shot on a four trax that I was given. I have it running finally, but now I can't stop. So last night I started on the brakes and I can't get the castle bolt off. Is this reverse thread, I thought of this on the way to work this morning, does anyone know what size this is. Went to the local ace, took my crescent wrench set to the size and tried a 1" deep socket to no avail. I am assuming that everything is metric on this atv, but they only had 28 mm and 30 mm. I am thinking that it may be 29mm, but I may be wrong. Also I can't get the thing to go in reverse, I push down the selector knob but it doesn't feel like anything is happening. Could this be because my handle brake feels like mush?

As far as reverse goes, and assuming everything is intact, there should be a cable connected to the left hand brake. Before you pull the brake, there is a button that has to be pressed down. Then pull the brake, and that should pull the cable that runs under the bike. While holding that, you can shift into reverse.
Yes, the button move is significant. There are two actions on the front brake. You should see the brake cable on the top, and the reverse cable on the bottom. If the button is not pressed, only the top action works. The button slides down (maybe half an inch?) to connect the bottom action. You can see the hand lever pulling the cable if it is working correctly. The button can only be pressed down if there is no pressure on the lever. ie. Push the button down first, and then pull the lever.
