I am assembling a huffy 16" girls princess bike and can not get the front wheel to attach to the fork one side will go in but the other side will not slide into position the bolts that keep the bearings in are interfering with the slots on the fork,

Mine had the same problem and there was no way bending the fork was going to work. It turns out they had installed an extral washer and nut on the axel. Take one off and retry fitting it. It may only go on one way. Make sure, before you tighten it, that the wheel turns freely.

Might be ... are there no breaks on the bike now? What kind of brakes are you talking about? Coaster (move the petals in reverse to activate) or hand. There should be a bracket on the front and rear forks to mount hand brakes. From your picture, the bike already has at least a front hand brake. The brake simply attaches to the bracket with a nut and bolt.

If you will go to a Bike shop in your community, I am certain they can give you assistance in operating the bike as it is now or adding additional brakes as you may deem appropriate.

Thanks for your question @ FixYa.com

You need to search on-line for the size of wheel, not by the model of the bike. Look at the tire, it will be labeled with the wheel size.

ONE AT A TIME, loosen the nuts securing the training wheels to the rear axle and slide each one upward a little bit so it float a little bit off the ground when the bike is vertical, then retighten the nut.

As she develops her handling and balance skills she'll need less help from the training wheel. So you can gradually raise them a bit higher as she masters balance and then she'll develop the 'lean' for turning. Ultimately, you remove them entirely.

I hope she's wearing a properly-fitted helmet.

The black plastic caps on the axle are just to protect the threads during shipping. You can throw them away. There may also be a plastic spacer on the front fork that keeps the fork from becoming bent together during shipping. This can be discarded too. good luck. Al K

spread the forks so the wheel will go in, it shouldn't hurt anything unless you break the

It's pretty hard to know how to help you exactly. But this may help--- if you have (or can borrow) a digital camera, take close-up pictures of your parts then take the camera with you to a Wal-mart or wherever this bike is sold. Compare your pictures to one on display. Or better yet, take the whole bike with you. Or just take close-up pictures of the bike on display. It might also be useful to know that the front fork (that is the two metal bars about 10 inches long that point toward the ground that the wheel attaches to) sometimes have to be spread apart just a bit to fit the wheel's axle in place. I'm talking about maybe 1/4 inch or so. If it's a lot more than that the fork may have gotten bent in shipment and you should take it back.
good luck, Merry Christmas. Al K

Huffy's general manual addresses only how to adjust brakes that have already been assembled (under the heading on page 20 it states "Adjustments". I noticed this problem and it took me a while to realize the single sheet of paper that came with the bike (not part of original manual), that acts as an addendum. It's called "Brake Cable to Brake Lever Assembly Instructions." Why this section hasn't been incorporated into the manual is beyond me.

tighten up the castle nut that holds the wheel yoke to the frame.

well forks might be bent loosen the nuts all the way off the rim now try squeezin the forks or pullin them apart depends on the problem...maybe this will help
