Adjusting bicycle brakes
There are several types of brakes for bicycles. The most common are the V-brakes, which are typical when two shoes pinch the rim, blocking it.
Secondly, the disc brakes are mechanical action. Come to be intermediate between the earlier and hydraulics, as the shoes, which in this case they are called pills, imprison a disk that is attached to the wheel, causing the brake.
The most advanced are hydraulic disc brakes. No doubt I recommend the stopping power, smoothness and low noise. They are more expensive but worth it.
Overall disc brakes have the advantage of being very quiet, compared with eerie screech of brakes V-brakes during hard braking.
also have better performance with water or mud.
Although they have the disadvantage that if we have a fall and we bend the disc, the wheel will remain locked. (Although this is unlikely to occur).
In my case, I have installed mechanical disc brakes. These brakes need to be taken very well regulated, because otherwise it can warp the disc and go grazing permanently, making it unpleasant.
Today I will teach you to regulate these brakes, and another time I will also how to adjust the others. In any case the end I have put a link so you can see how to adjust the V-brake.
Basically, mechanical disc brakes have two settings: the cable itself, which holds a brake pad at the precise distance of the disc, and a screw used to adjust the distance of the pickup opposite side of the disc.
precisely the drawback of these brakes is that a tablet is fixed, moving just the opposite, you press the disc against the fixed pad. Hence the importance of having them very well regulated.
First, we must see if the pads are worn. If takes relatively little time with the bike that is unlikely. But if we have doubts, it is best to remove the pads by pulling them with needlenose pliers, and examine if worn. The
we put in case they are in good condition and proceed with the handle, as the pill is going to spend, we noticed that the handle needs to be tightened further, because the pill needs to do more travel to reach the disk.
can easily adjust it by acting on the nut that secures the brake cable: subjects with cable pliers, loosen the screw and pull a little cable. We return to tighten a little and check. If OK, we'll give you a grip to the screw. That if carefully with pliers. Should hold the cord, the cap having at the end of auction, then we can remove the cable and deshilacharĂa.
In many cases, we have a nut on the opposite side of the brake cable at the base of the handle corresponding to turning, we will adjust the cable.
Once this adjustment, we turn to the other pad. Right now, we have the wheel spins freely, without friction. Look on the inner face of the brake and see three nuts: two black used to set the brake itself to the box and a larger bike.
É This is the we play. But we will move very slowly and examining how it behaves on the brakes. Sufficient turning 1 / 8 turn at a time or less, if possible, until it is as tight as the disc without touching him when the wheel turns freely.
Sometimes the disc is slightly warped and a light touch is inevitable at some point. That is, as I say, inevitable. The important thing is that the wheel turns freely. With use, the friction will be minimized. Of course, if you like the brake lever has more game, so it starts to slow down when it has reached the halfway mark, we will give more clearance to the pill. Personally, I prefer that the brake begins to act just start pressing the lever.
We do a thorough cleaning with a rag and alcohol to remove any grease, even the fingers, touching the disc and we already have about brakes.
If the reader is reading this right now is to buy a bike and do not know what to decide, I recommend, if you can afford, hydraulic disc, then squeeze the two pads to the time, so that the disc is not deformed. Apart from the braking is much more powerful and progressive.
not forget that we are doing a mechanical job. Worn clothing for this purpose.
