1516:' race, where riders almost certainly would need to repack their coaster brakes after the grease melted or smoked due to the heat from lengthy downhill runs. A coaster brake can only be applied when the cranks are reasonably level, limiting how quickly it can be applied. As coaster brakes are only made for rear wheels, they have the disadvantage common to all rear brakes of skidding the wheel easily. This disadvantage may, however, be alleviated if the bicycle also has a hand-lever-operated front brake and the cyclist uses it. Another disadvantage is that the coaster brake is completely dependent on the chain being fully intact and engaged. If the chain breaks or disengages from the chainwheel and/or rear sprocket, the coaster brake provides no braking power whatsoever. Like all hub brakes except disc brakes, a coaster brake requires a reaction arm to be connected to the frame. This may require unbolting when the wheel is removed or moved in its fork ends to adjust chain tension.

contacting the tyre, thus braking the front wheel. A tension spring held the rollers away from the tyre except when braking. Braking power was enhanced by an extra-long brake lever mounted in parallel with and behind the handlebar, which provided additional leverage when braking (two hands could be used to pull the lever if necessary). Used in combination with a rear coaster brake, a cyclist of the day could stop much more quickly and with better modulation of braking effort than was possible using only a spoon brake or rear coaster brake.

clearance; with rim brakes, this would be impossible, as the different rim sizes would not allow the same rim brakes to work with a different sized wheel. Wheel size optionality with disc brakes allows the rider more options, including using a smaller diameter rim-sized wheel (such as 27.5″+) with a higher volume wider tire with the same outer diameter size as a larger rim-sized wheel (such as 29″) – the outer diameter consistency is important as it preserves the geometry of the frame between the two different wheel sizes.

brakes. Mechanical (i.e. cable-actuated) disc brakes use the same amount of cable travel as V-brakes, except for those that are described as being "road" specific. As a general rule, mechanical disc brakes for so-called "flat bar" bicycles (chiefly mountain and hybrid bicycles) are compatible with V-brake levers, whereas mechanical disc brakes intended for "drop-bar" bicycles are compatible with the cable pull of older brake designs (cantilever, caliper, and U-brake).
145:, were similarly braked with a spoon brake or by back pedalling. During its development from 1870 to 1878, there were various designs for brakes, most of them operating on the rear wheel. However, as the rear wheel became smaller and smaller, with more of the rider's weight over the front wheel, braking on the rear wheel became less effective. The front brake, introduced by John Kean in 1873, had been generally adopted by 1880 because of its greater stopping power.

to wear unevenly. Over longer time and use, rims can become worn. Rims should be checked for wear periodically as they can fail catastrophically if the braking surface becomes too worn. Wear is accelerated by wet and muddy conditions. Rim brakes require that the rims be straight (not out-of-round or warped). If a rim has a pronounced wobble, then the braking force may be intermittent or uneven, and the pads may rub the rims even when the brake is not applied.

On the downside, their shorter arms provide very small tyre and wheel clearance and generally make for a less forgiving setup: they can only accommodate smaller tyre sizes compared to cantilever brakes, may pose problems for mounting fenders, can be clogged more easily by mud, and they can make it harder to change wheels.

Cross country bicycles usually use smaller rotors which handle smaller loads but offer considerable weight savings.

Dual-pivot brakes are slightly heavier than conventional side-pull calipers and cannot accurately track an out-of-true rim, or a wheel that flexes from side to side in the frame during hard climbing. It is common to see professional racers climbing mountains with the quick-release undone on the rear brake, to eliminate drag from this source.

In recent years post mount has gained ground and is becoming more common. This is mostly due to decreased manufacturing and part cost for the brake calipers when using post mount.

not necessarily provide more braking force, but will wear more slowly (in relation to thickness), so can usually be thinner. In general, a brake can be fitted with a variety of pads, as long as the mounting is compatible. Carbon fiber rims may be more sensitive to damage by incorrectly-matched brake pads, and generally must use non-abrasive cork pads.
753:. Because the arms move only in their designed arcs, the brake shoe must be adjustable in several planes. Thus cantilever brake shoes are notoriously difficult to adjust. As the brake shoes of a second-class cantilever brake wears, they ride lower on the rim. Eventually, one may go underneath the rim, so that the brake does not function.

As the cam presses against the follower, the force is also transmitted to the other arm via the link. And specifically for suspension forks where the housing must terminate at the brake frame, the side-pull "sabre cam brake" was developed.

Disc brakes require a hub built to accept the disc, and a fork (for front brakes) or frame (for rear brakes) built to accept the caliper. Front hubs designed for discs often move the left hub's flange inward to make room for the disc, which causes the wheel to be dished. A dished wheel is laterally
