Riding a bike is an incomparable pleasure. A constant wind in your hair, a feeling of complete freedom and independence, besides cycling can replace constant trips to the gym, it's no secret that riding on a “two-wheeled” affects absolutely all muscle groups. First of all, legs, back, arms, press - all this is maintained in an active tone due to the bicycle load. The benefits of the bike can not be diminished. But in order to enjoy walks from day to day, you need to care for your “horse”. Just as preventive work attributed setting brakes.
Safety first! Yes, this rule is worth remembering every time you want to ride a bike. Indeed, many "ordinary" walks end up with injuries. And most often the cyclists themselves are guilty of the accident. It is their carelessness that leads to grave consequences. Inattention - what can be meant by this? First, the dismissive attitude to the very object of driving, namely, to the bicycle itself. Malfunction it often is the cause of unwanted injuries.
Bad brakes are a problem for every rider. I do not really want to check before each trip. It is tiring and time consuming. But the problem is - it is necessary. Routine brake testing can save lives and stay healthy. Adjusting the brakes on a bike is a painstaking exercise. Therefore, it is important to be able to do it right.
Varieties and models of bicycle brakes
Adjustment of the brakes on the bike may be different. In each situation it is worth looking at the type of brake system. Most often, cheap bikes are equipped with mechanical rim brakes, or, as they are also called, V-brakes.
They are easy to use, cheap, and their parts are easily replaced. But, unfortunately, everything cheap has its disadvantages. The rim brake is not a priority in its class. This is due to its design. Pads often do not pinch the moving part as necessary, so the stopping distance becomes quite large. But expensive mechanical brakes can be quite competitive. In general, the adjustment of V-brakes on a bicycle does not require much effort, special techniques, so this class will be suitable for beginners and amateurs.
Mechanical disc brakes
Everything is on the rise. And as you can guess, disc brakes rank second in the list of systems of this type. What kind of changes can be seen here? All the same levers, the same metal cables. Only the brake itself is changed. Now the disk is bolted to the bicycle wheel. Nearby there are two clamps with pads. Yes, the disc wheel is in direct contact with the clips.
This innovation increases grip. Now, if you hold the lever down, the wheel will not spin. That is why the disc brake is installed on sports bikes. With him the braking distance is halved. And this is what you need to achieve. Adjusting disc brakes on a bicycle differs from rim tuning. Therefore, it is not easy to travel all your life on V-breaks, and then switch to disc brakes. After all, you have to learn again to configure this system.
Hydraulic disc brake
So, the winner of the rating. It is hydraulics that rules the world of brakes. How does this system work? There are handles, there is a disk and there are braking elements. They are connected together by rubber tubes, inside of which there is oil, or, as it should be properly said, brake fluid. What are its pros and cons? Hydraulics accurately respond to any press. It can be said instantly conveys pressure. That is why many athletes and extreme lovers put on their bicycles hydraulic disc brakes. After all, the exact transfer of sensations helps to win important seconds. The hydraulic brake firmly squeezes the metal disc so that with a sharp pressing the rider can fly out of the saddle in the truest sense of the word. But, like everyone, hydraulics has its negative sides.
First, the high cost. This, of course, is a dubious minus, because this system is not bought by ordinary amateurs, but by professionals. Secondly, the issue of fixing. Yes, it's just impossible to repair the hydraulics yourself. The slightest upset - and a trip to the workshop is provided. And again, the repair will cost a pretty penny. System nodes such as tubes are not very reliable. If this part breaks, brake fluid leaks. Therefore, it will be possible to brake only with your feet. Adjusting the hydraulic brakes on a bike is a tricky business. This, if possible, is better to entrust 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 simplest brake system - rim. V-breaks are not famous for ingenuity. Simple as two and two device. What is the system of this mechanical brake? There are levers that are mounted on the steering wheel. There are tubes (correctly called “shirts”), inside of which an iron cable fidgets. Two clamps and pads. Everything is nothing more. That is why there are only three provisions for 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 pads. 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 pick up the brake.
Adjusting the rear brakes on the bike
Theoretically, everything is clear. Three parameters, three actions, and only one result - well tuned brakes. Once again - this is in theory. In fact, it is difficult for newcomers to do everything perfectly. Adjusting the rim brakes on a bike is a subtle thing. Therefore, you first need to be patient.
So the first step is to adjust the pads. They should be directed parallel to the rim both on the rear wheel and on the front one.
Especially do not tolerate the shouting of the item on the tire. A couple of kilometers - and the tires will rub to the holes. It is undesirable for the shoe to also go beyond the wheel. From this, it is quickly erased, but there is no desirable effect (good braking). Therefore, it is important to properly adjust the position of the brake pads. Adjusting the mechanical brake on the bike begins with the selection of tools. You will need: a hex, a screwdriver and a wrench for 12. For rubber clips, you should only take a hex. It is worth starting with holding the brake lever. From this pads will cling to the rim. After examining the situation, you can immediately see where something is wrong. This tool is worth loosening the puck. Then, while holding the brake lever, align the rubber clip in the desired direction. The same should be repeated from the other side. This is just the first step towards a perfectly tuned brake.
Front bike brake adjustment
The most difficult thing to come. Do not be afraid, you just need to concentrate. So, you need to adjust the distance between the pads and the wheel. It is important. Again, action monitoring is similar for the rear and front brakes. It is worth remembering: if the distance is too large, the clamps will not fit well. Therefore, the braking effect will not be. If, on the contrary, there is not enough space left for the brakes, they will strike the rim. From this pads will quickly erase, and the wheel will constantly brake. In general, the distance between the pads and the rim can be adjusted using one nut, which is located on the levers, on top, where a metal cable is attached.
It should be unscrewed, thereby loosening the grip. From this action levers go, do not be afraid. With their hand strength you need to lean against the rim. Then hold the brake handle so that it does not reach the steering wheel a couple of centimeters. Holding the levers in the same position, you should re-tighten the nut. Adjusting the brakes on a bike is not limited to this.
The springs that are included in the system of rim mechanical brakes are also responsible for the distance between the wheel and the pad. But, unlike a nut with a cable, they allow you to adjust the distance up to the millimeter. That is more accurate. The tension of the spring can be changed with a single bolt, which every now and then twists and twists. This bolt is located on both sides of the brake. Therefore, when a situation arises that one side touches the rim and the other separates, you just have to tuck the bolt and everything will fall into place. When this element is tightened, the spring becomes “harder”. Consequently, the distance will increase. If you unscrew the bolt, the spring will loosen. From this distance will decrease. So, by adjusting each element, you can achieve perfect accuracy.
Adjustment of disc brakes on a bicycle is carried out with just two cogs. The first is responsible for the distance between the disc and the pad. The second is responsible for its location in the vertical plane. Therefore, if the rubber clips are constantly hurt the brake or, conversely, the disk came out of the "touch zone" of the pads, you just have to work with a screwdriver. Through trial and error, you can understand what is responsible for what, and then - the matter of technology. Turning the screw, you can immediately adjust the position.
Hydraulic disc brake
Adjusting the brakes on a bike equipped with hydraulics is difficult. For this you need to have special tools and special skills. But you can do everything to breakdowns did not occur. That prevention will help hydraulics not to break down and serve the owner for a long time.
