Depends on what kind it is. If it's a rim brake, setting the pads up with more toe- in usually fixes it. check out the links below for more for more.
Depends on if it's a disc brake or rim braked bike. And then there are differences between brands. Head over to www.parktool.com, www.bicycletutor.com or www.sheldonbrown.com to find out more. For disc brake bikes, see if you can identify the brand, then go visit their website. They often post maintenance instsructions there.
The tire could be rubbing if you have oversize tires, or aftermarket rims. The only other cause would be a failure of a part in the brake system.
Somewhere, a stationary brake pad will be pushed against a moving surface. If the bike is rim braked, brake pads will pinch the wheel rim. If the bike is drum or coaster braked, stationary pads will push out against the rotating shell of the hub. If the bike is disc braked, brake pads will pinch the rotor between them. And the friction between the moving surface and the stationary brake pads (together with the friction between tires and ground) is what stops the bike.
They're called brake bosses, and you use then as attachment points for a certain type of rim brake.
The wheels of a bike get very hot when braking hard due to the conversion of kinetic energy into thermal energy. When you apply the brakes, the brake pads rub against the rim of the wheel, which creates friction. This friction slows the bike down, but it also generates a lot of heat. The heat is transferred from the brake pads to the rim, which is why the rim gets hot. The amount of heat that is generated depends on a number of factors, including the speed of the bike, the force of the brakes, and the material of the brake pads and rim. In general, the faster the bike is going and the harder you apply the brakes, the hotter the rim will get. If you brake too hard or for too long, the rim can get so hot that it can warp or even melt. This can cause the tire to blow out, which can be dangerous. It is important to brake smoothly and gradually to avoid overheating the rim.
Brakes will squeak when the brake shoes vibrate on the rim of the wheel as they grab. As the rim rotates, it will twist the brake shoes so that only the back of the show touches the rim. To fix this, you need to make sure your brakes have what's called "toe in". Essentially, the brake shoes should be angled in such a way to where the front of the brake shoe touches first. Then, as the rim and brake shoe meet, the brake will flex in and the shoes will grab flush into the rim and not squeak.
It's no trouble at all using supposedly rim brake rims with disc brakes, nothing will happen because of that. But your hubs has to be able to take a brake rotor and your fork/frame has to be able to take a brake caliper if you want to put disc brakes on your bike.
well, firstly, he sat on it, THEN he rode it and bukled his back rim landing 180's rearly REARLY hard. is 'How did ben brake his bike?', a metothorical question? because what i think is, the bike broke its self when he saw ben walk in to the shop to buy it. thanx, Anomunous.
A 2003 Lexus with an intermittent grinding noise might mean that there is a tire rim rubbing on the brake disk. It could also mean that a tire is rubbing on a fender wall when turning.
That depends on a lot of things. If it's for a rim-braked bike that gets ridden in dirt/mud, then braking will eventually cause the brake track of the rim to wear out. Depending om how much you ride this will take anything from a single year to ages. If it's on a rim braked bike that is only used under good conditions rims can also last pretty much forever. If it's on a hub braked bike, there's no real limit to the life of the rim either. But OTOH hitting a single pothole/curb can destroy the rim immediately. Overtensioning the spokes can also kill a rim quite rapidly.
What are they rubbing on? If it is the control arms, you need a spacer between the hub and rim.
