STUCK REAR BRAKE ON KIDS BIKE

How do I unstick a rear brake?
It's on a kid's bike and it's operated by a brake lever
or the pedals. I have tried squeezing and releasing the
brake lever, stepping hard on pedals, and manually pulling
the brake pads off the wheel rim. Thought I'd check with
you before taking it to the store. Thanks.
A quick fix: Where the cable comes
out of the brake lever, youll see a little metal barrel
you can turn with your fingers. See if you can turn it so
it moves toward the brake lever. If it does, it might unstick
the brakes enough for the wheel to move.
As far as the cause, Ill bet
the bike has one of these problems:
1. The rear wheel has gotten bent:
First look to see if only one of the brake pads rubs the
wheel. If so, you might fix it by centering the wheel. Loosen
the nuts that hold the wheels axle, use your hand
to push the wheel so that it centers between the brake pads,
then tighten the axle nuts. If both pads rub at the same
time, see below.
2. The brake cable has broken: Find
the end of the cable where it sticks out of the brake. Grab
it with pliers and pull hard. If it comes off, it needs
3. The brake cable has come loose
from the brake: Pull the cable as above. If you can at first
pull it thru the brake assembly and then it stops, it might
just have come loose. You can see how to tighten the cable
by going to one of the Park Tool pages
on repairing brakes. (Go to the bottom of the list and
look at each brake type to see which one applies.)
