not enough info to answer....it is hard to explain you just have to get the spring tight along with the brake cable and the brake pads as close to the rim with out rubbing....try adjusting the tiny screw that looks like it does nothing right next to the spring

Go top sports authority and buy a little kit with the lacing and the tool to do it with.  There should be some instructions in there.

There may be too much brake fluid in the rear brake reservoir tank.\n\nbut cannot be too sure unless yo specify the make and model of brake unit.  Shimano offers details for servicing disk brake systems.

You should probably get new tubes and also tires.  Just check the size on the sidewall of the tire and buy tubes to match.  If you are unsure of your tire/tube changing skills then take your bike to a dealer and have them do it for you.  You should also get an inspection/tune up while you're at it since you haven't ridden it for so long.

The chain could be loose or your gears need adjusting. You should take it down to your local bike shop and ask them to fix it for you.

Sometimes new bikes need a little breaking-in (like shoes) so don't worry too much right now.  But if its a loud squeak then maybe the ball-bearings in the hub need some more lubrification.  \nIt could even be coming from the stem as well, as you get up out of the saddle you put more weight on the handle-bars the steering tube might be getting rubbed. \nIf you got the tools its easy to apply some lube but if not you should take it to a bike shop.\nAlso check the spokes to make sure they are all the same tension because the wheel could be flexing and rubbing the brake pads (maybe).\nGood luck.

Lift the bike above your head with one hand and apply the oil with the other while using your head to rotate the pedals \n\nImportant safety precaution: Wear goggles to keep oil splashes out of your eyes and a crash helmet because the pedals keep hitting you in the back of the head and then you drop the bike.\n\nEasy!!

A lot depends upon the duration and intensity of the ride, but as a rule of thumb after each ride;\n\nWash the bike, then spray the chain with WD40.  Let it dry and then lube the chain with a quality chain lube.  Inspect the air filter, it may not need cleaning, but I usually clean and service it after each ride/race.  I also change the oil after each ride/race, you can go longer, but I wouldn't go longer than 3 or 4 rides/races with out changing the oil.  Check all the nuts and bolts, controls, cables and brakes.\n\nBefore you ride, bleed the air off the forks, adjust the air pressure in your tires and your suspension settings according to the terrain you will be riding in.\n\nYour manual is going to recommend replacing the rings every six hours of use or so.  I prefer to keep up with the compression readings, my rule of thumb is 120 p.s.i.  I usually rebuild the top end every winter during the off season so that I start the new season with a fresh top end.\n\nBasically just keep a close eye on things.  You can usually see a problem developing and preventive maintenance is much cheaper than repairing something that breaks due to negligence.

An 8mm Allen wrench can be used to tighten the crank to the bottom bracket.  On some older models, a 14mm or 15mm hex head wrench would be used.  However, if the bottom is what is actully loose, you usually have to remove the crank, tighten the bottom bracket, and then replace the crank.\n\nYou should probably take this to your bike shop if you don't understand what I've said above.

well u have ball barings were the handle bars conect to the the frame and u have them under neath, were the forks connect to the frame, u take a wrench, pop the nut of the top then you pull the th forks and the handle bar out away from ecother, but be careful, watch the way the barings are, so you dont lose them, then after you grease them you just put it back together the way it came apart.

they are supposed to be, BMX bikes are designed for stunts and tricks,so they make them smaller and lighter

In addition to the above answers, look at how the cable is routed - any sharp bends, or the cable not being seated properly in the levers will give you a hard time. If you raised the bars it will raise the cable housing with it, and it will now be too short and causing the brakes to drag or be inneffective.\n\nWhat type of pads did you replace the old ones with? If department store-type, you can't expect much from these. Get some decent pads from the bike shop and give it another go if this isi the case.\n\nThe brakes themselves may be adjusted too tight or corroded at the pivot point(s). They should easily move back to thier resting position if you squeeze them by hand.\n\nAlso, if you have linear-pull (or "v") brakes and a lever designed for sidepulls or cantilevers you can adjust all day and not get any better. Soemtimes, on department store bikes, these are mis-matched right from the factory and you'll need to get the correct levers for the brakes.

I'm assuming you mean basic hub assembly, or possibly just putting the rear cassette back on. But possibly you mean spokes and rim assembly and 'true'ing' the wheel.\n\nRegardless of how bad a state you back wheel is in, you will likely need specialist bike tools to complete the task. I know it took me a while to obtain the right tools and I was only swapping my rear cassette from my original wheel onto a new one that I had bought.\n\nSo assuming you now have the right tools and dont want to pay a bike shop to do the task (Very understandable), I recommend you use one of the following websites. They are very informative, step by step pictures provided for all your repair needs.\n\nhttp://www.parktool.com/repair/\nProbably the best.\n\nhttp://www.bikewebsite.com/repair-bike-index.htm\nAlternative option to try.
