This is the rear brake on my son's bike. The right pad on the caliper is riding on the rim. Actually, it seems like the caliper isn't releasing on either side as it should. This should be a simple adjustment, but I don't know how to do it. Suggestions?

May want to bring it into a Bike Store. They usually diagnose for free.
Last time I worked on my mountain bike, I ended up disconnecting the rear brake

That's a good thought, and my local should would do it for free. I'm trying to save the time, though. My boys are home from school, and I need to get them outside and away from the video games!

Tried loosening this little nut here and adjusting the location that it clamps the cable?

Is this a tension issue with the brake cable?

There's usually and adjustment on the brake pads themselves that lets you move them in and out as they ware down. Move them out so there is more space between the pad and the wheel.

If you're in a tight pinch release the rear brake completely and tell them to use the front, gingerly of course!

See that little black screw poking out sideways, right next to the brake post mount? Turn that clockwise a little bit, it puts tension on the silver tension spring. Turn about a half turn and squeeze the brakes to actuate the spring, repeat a few times until the gap between the pads and rims on both sides are equal.
Also, I haven't watched this all the way yet, but it should guide you through the process.

Could be an issue with being too tight here, or with the pad being adjusted to close to the tire and catching drag while retracting. Or, the spring may not be up to snuff.
In any case, I'd say attempt to rotate it there some, if the springs are balanced and the levers can move on the pins as they should, it'll be about as hard to push it left as it is to push it right (both levers together). If not, you should be able to feel out the binding.

That's a thought. It's got a single rear brake plus coaster brakes. So stopping is still possible.

I turned those a bit, and nothing seemed to happen. But I'll try again. Thanks for the vid.

I could try to explain, but a short video is better.
I had the same problem with my nieces' bike. Cheap kid's bike components seem to need a little more finicking & readjustments than high quality bikes do.
Unless you can see that the brake pads themselves are making wacky contact with the rim, don't bother with them. They can be a pain to set up just right.

This right here. Can be a bit fiddly though and you may need to use the little black screws for tenstioning the spring afterwards to ensure that both pads are equally spaced from the rim.

Try releasing this and pushing the pad back a little or take the back brake off completely and even out the pads or move the wheel over to the other side trust me one should work I had to work on my bike yesterday apparently when you put a motor from the local dump on it it likes to throw it's chain and destroy it's brakes.

more often than not, you'll see a gimpy side to the brakes where it seems to rub instead of release. Unless it makes you nervous, try to center the brakes, tighten, and keep riding. It will mess itself up again over time, and is damn near impossible to permanently fix as far as I know. I havent noticed uneven wear on my own bike, and i dont seat it. Couple thousand miles on my brakes right now, and theyre still good for another couple thousand at least.

I punted and took it to the shop. His brother's bike was making a weird clicking noise when pedaling. I've got free service for a year, since I just bought them last October. But brake adjustment ought to be something I can do myself. I'm going to ask the tech what he did, and how I can do it myself in the future. Thanks for the video.

I never bother with those, just flip the spring out of its stop, bend it a little (a little) and put it back. it works better and lasts longer. you don't need my credentials as a bike mechanic, but I has them.

Just sit 'em down with dave mirra's bmx adventure 2015 or whatever it's called these days and let them pretend like they're out biking

You can see the spring here, pull the spring around the tab to free it, then just slightly bend it back and put it back in place till you are close, then use the screws for fine tuning. 5 second fix!

They'll only make that mistake once.
