brake and alignment

let me ask you about my schwiinn world sport brake. I believe there are 2 brake arms put together to grab onto the rim, right? ok, there's a nut infront of the brake arms to hold them together. But the NUT
unscrews by itself when i keep using brake. If i tighten the nut tight, then the brake lever doesnt release.
i don't know how to hold it into place.

2) alignment: After i changed the tires, it seems like the bike doesnt go straight when i let go of my hands. It went straight before i changed the tires. Maybe it's because i took out the rear rim and didn't put it back in right?

It seems like the rim is placed to the left instead of dead staight. But I don't think the rim can go to the right nomore...

how do i check if the rim is aligned? how do i fix?

1) I bet you're missing some washers from the stack, or they're in the wrong place.

2) Probably. How does the rim mount? Nuts?
