Reposting this verbatim in new thread because it seems once bqg

Your seat issue is probably just a carriage bolt.
Take off the seat, the without taking the bolt all the way out, smack that shit with a hammer and it should be able to come up and down now.
Your stem might also be this way if it's a shitty dept bike.

Check out your derailleurs and make sure the teeth aren't all worn down, too.

What do you mean your brakes 'grab at different times', like while you're riding and not touching them? Then they're cockeyed or your wheels aren't true.

The brakes will grab at different points of pressure when I grab. Instead of a steady increase of pressure it'll randomly grab harder even though I'm holding the brake at the same pressure.

I also checked the action of the brake itself and the rim of both tires. Both don't have any visual blemishes and the same surface, and from what little I can tell the wheels and brake assembly seem to be on aligned and straight. When I spin the wheels I don't see any wobble. When I use either brake though, one side pad of the brake contacts before the other, and the pressure I need to put for both to touch changes every pull by a little bit.

Is it worth buying a new stem and fixing the brakes and shifters or just getting a better bike?

You don't need a new stem or a seat post, like I said, take your time and smack the shit out of it.
I trash picked an 80s dept bike, made in mind with the buyer never actually going to ride or adjust it, a fashion item, and it took me a good half hour of smacking and wiggling before anything started to move.

As for the brakes, I dunno. Wouldn't be too hard to get new ones.
So long as they stop you, I wouldn't worry about replacing them until you just straight get a new bike.

In short, adjust your seat, and keep using it meantime, but think about another bike because your's sounds like shit.

Alright, thanks for the help
