Cycling is an incomparable pleasure. A constant wind in the hair, a feeling of complete freedom and independence, besides cycling can replace permanent trips to the gym, it's no secret that riding on a "two-wheel" affects absolutely all muscle groups. First of all, legs, back, hands, press - all this is maintained in an active tone thanks to bicycle load. Benefit from the bike can not be understated. But in order to enjoy walking every day, you need to look after your "horse". Just for preventive works carry the setting of the brakes.
Security is above all! Yes, this rule is worth remembering every time you want to ride a bike. After all, many "ordinary" walks end in traumas. And the cyclists are the ones who blame the incident most often. It is their inattention that leads to serious consequences. Inattention - what can we mean by this? First, a disdainful attitude to the object of the ride itself, namely to the bike itself. Its malfunction often leads to undesirable injuries.
Defective brakes are a problem for every cyclist. I do not really want to check before each trip. It is tedious and time consuming. But that's the problem - it's necessary. A routine check of brakes can save lives and keep health. Adjusting the brakes on the bike is a painstaking task. Therefore, it is so important to be able to do this correctly.
Varieties and models of bicycle brakes
Adjustment of brakes on a bicycle can be different. In each situation, it is worth looking at the type of brake system. Most often cheap bicycles are equipped with mechanical brake brakes, or, as they are called, V-brakes.
They are easy to use, cheap, and their parts are easily replaced. But, unfortunately, everything cheap has its drawbacks. Brake brake is not a priority in its class. This is due to its design. Pads often do not clamp the driving part as it should, so the braking distance becomes quite large. But expensive mechanical brakes can be quite competitive. In general, adjusting V-brakes on a bicycle does not require much effort, special techniques, so beginners and amateurs of this class will do.
Disc mechanical brakes
Everything goes on increasing. And as you might guess, the disc brakes take second place in the list of systems of this type. What changes can you see here? All the same levers, the same metal cables. Only the brake itself is changed. Now a wheel is attached to the bicycle wheel. Next, there are two clamps with shoes. Yes, the wheel wheel is directly in contact with the clamps.
This innovation increases grip. Now, if you clamp the lever, the wheel will not scroll. That's why the disc brake is installed on sports bikes. With it, the braking distance is halved. And this must be achieved. Adjustment of disc brakes on a bicycle differs from the technique of tuning the rims. Therefore, it can be difficult to travel all your life on V-breaks, and then go to the disc brakes. After all, you'll have to learn how to set up this system again.
Disc Hydraulic Brake
So, the winner of the rating. It is the hydraulics that rules the brakes in the world. How is this system arranged? There are pens, there is a disk and there are braking elements. They are connected together by rubber tubes, inside of which there is oil, or, as we should say, the brake fluid. What are its pros and cons? Hydraulics accurately reacts to any pressing. You can say instantly transmits pressure. That's why many athletes and extreme sportsmen put their hydraulic disc brakes on their bicycles. After all, an accurate transmission of sensations helps to win important seconds. The hydraulic brake tightly compresses the metal disk so that when pressed hard, the rider can fly out of the saddle in the truest sense of the word. But, like everyone else, hydraulics have their negative sides.
First, high cost. This, of course, is a dubious drawback, because this system is not bought by ordinary amateurs, but by professionals. Secondly, the issue with fixing. Yes, it's simply impossible to repair hydraulics yourself. The slightest frustration - and a trip to the workshop is assured. And again, the repair will fly in a pretty penny. Such nodes of the system as tubes are not very reliable. When this part is broken, the brake fluid flows out. Therefore, it will be possible to brake only with the feet. Adjusting hydraulic brakes on a bicycle is difficult. This, if possible, is best entrusted to the master.
The first steps in the repair and adjustment business
As always, first you should start with a simple one. In this case - with the repair of the most simple braking system - rim. V-breaks are not famous for their ingenuity. Simple as a two-two, device. What is the system of this mechanical brake? There are levers that are mounted on the handlebars. There are tubes (it's correct to call them "shirts"), inside of which the iron rope is fidgeting. Two clamps and pads. Everything is nothing more. That is why there are only three provisions on which it is necessary to regulate the V-break.
The first is to control the distance between the pads and the wheel. The second is the control of the direction of the shoes. The third is the degree of tension of the clamps. For beginners this may seem difficult, especially in practice. But experienced lovers in just seven minutes can assemble the disassembled brake.
Adjusting the rear brakes on the bike
In the theoretical plan, everything seems to be clear. Three parameters, three actions, and only one result - well-adjusted brakes. Once again - it's in theory. In fact, beginners find it difficult to do everything perfectly. Adjusting the brakes on the bike is a delicate thing. Therefore, you must first have patience.
So, the first step is to adjust the pads. They should be parallel to the rim on both the rear wheel and the front wheel.
Especially do not tolerate the chirping of this element on the tire. A couple of kilometers - and the rubber will rub through to the holes. It is undesirable for the shoe to also extend beyond the wheel. From this it is quickly erased, and there is no desired effect (good inhibition). Therefore, it is so important to correctly adjust the position of the brake pads. Adjusting the mechanical brake on the bike begins with the selection of tools. You will need: a hexagon, a screwdriver and a key for 12. For rubber clips, it is necessary to take only the hexagon. It starts with holding the handle of the brake. From this, the pads will be pressed against the rim. Having inspected the situation, you can immediately see where something is wrong. Use this tool to loosen the washer. Then, just holding the brake lever, align the rubber clamp in the desired direction. The same is worth repeating on the other side. This is only the first step on the road to a perfectly tuned brake.
Adjusting the front brake on the bike
The most difficult is ahead. Do not be afraid, you just need to concentrate. So, you need to adjust the distance between the shoes and the wheel. It is important. Again, monitoring actions is similar for the rear and front brakes. It is worth remembering: if the distance is too large, the clamps will not fit properly. Consequently, there will be no inhibitory effect. If, on the contrary, leave the brakes a little space - they will be struck on the rim. From this pads quickly erased, and the wheel will constantly brake. In general, you can adjust the distance between the pads and the rim by using one nut that is on the arms, from above, where a metal cable is attached.
It's worth to unscrew it, thereby loosening the grip. From this action the levers leave, do not be afraid. Their strength should be leaned against the rim. Then tighten the handle of the brake so that it does not reach the steering wheel for a couple of centimeters. While holding the levers in the same position, turn the nut back on. Adjusting the brakes on the bike is not limited to this.
The springs that enter the system of mechanical brake brakes are also responsible for the distance between the wheel and the shoe. But, unlike a nut with a cable, they allow you to adjust the distance up to a millimeter. That is more accurate. The tension of the spring can be changed with a single bolt, which now and then is twisted and unscrewed. This bolt is located on both sides of the brake. Therefore, when a situation arises that one side touches the rim, and the second is separated, it is only necessary to turn the bolt - and everything will fall into place. When this element is twisted, the spring becomes "firmer". Consequently, the distance will increase. If you unscrew the bolt, the spring will loosen. From this distance will decrease. So, by regulating each element, you can achieve perfect accuracy.
Adjustment of disc brakes on a bicycle is carried out by only two cogs. The first is responsible for the distance between the disc and the shoe. The second is responsible for its location in the vertical plane. Therefore, if the rubber clamps began to constantly touch the brake or, conversely, the disc came out of the "touch zone" of the pads, it is only necessary to work with a screwdriver. Through trial and error you can understand what is responsible for, and then - the matter of technology. Turning the screw, you can immediately adjust the position.
Hydraulic disc brake
Adjusting the brakes on a bicycle equipped with hydraulics is complicated. For this you need to have special tools and special skills. But you can do everything to prevent breakdowns. Precisely prevention will help hydraulics not break down and serve the owner for a long time.
