As an amateur rider, he likes his favorite bicycle exercise and can master certain maintenance methods and skills. This will undoubtedly add brilliance to his cycling life; he believes that many fans and friends will adjust their own long love. ! ! What I want to say here today is to debug the brake system myself. Because I found that too many brakes are unsatisfactory riders, here, combined with my many years of experience and maintenance experience, and some riders to make some discussion, the right to make a fuss! Please do not laugh at all! Thank you! ! Brake can be divided into several types in the present: hydraulic disc brakes, wire brake discs, hydraulic V brakes, line pull V brakes, and suspension brakes, ordinary brakes, and so on. There are many kinds of brakes, which are not listed here. The focus now is to talk about people using more V-brakes; as far as I know, 87% of mountain bikes are used V-brake, and some also use V-brake for road bikes and station wagons, so the V-brake is The proportion of riders in the more! Do not be self-righteous that V-brake can not reach the effect of hydraulic brake or hydraulic disc brake. After reading it can be confirmed - it can be achieved, even more than the oil brake! ! First, the brake line to be selected, the outside line should have a layer of plastic inside, the general SHIMANO has, the inside line should also be of good quality, to resist some of the SHIMANO can be, the handbrake part, is commonly known as The brake lever; believe that the average person will use Siamese pointing, it would be better, such as SHIMANO EF-29, this does not need to focus on the explanation; split brake lever, SHIMANO M420 or M510, are all possible! Second, the selection of V-brake is a relatively simple matter, the price can determine the quality, ¥ 40-50 yuan V brake, the performance is certainly not much better, and its rotation is directly with the frame bracket screw The use of a long time is not good for making seat nails, so when you buy it, you should look good; a better V-brake generally has a rotating seat, and there is no friction when the brake is turned and the seat pin is used to protect the frame; Please refer to SHIMANO--M420 OR M600 for reference. These V-brakes all have rotating seats. Special tips: Some inexpensive V-brakes have relatively soft brake arms, and naturally do not perform well when braked, making them less than ideal. The effect! Choose a good, you can install the V-brake on the frame, when installed, do not have to install brake pads, first try the brakes is not smooth, with particular emphasis: do not forget to forget about some oil on the brake core! ! Tips: The brake wire core must not be placed "butter", "butter" is the bearing oil, it's great adhesion! Used in the brake wire core to impede the pull of the brake wire, that can be counterproductive! Put oil to put oil, such as sloping stone, ZEFAL is very good, very economical! ! If you feel good, you can install brake pads. The brake pad screws also need to put some oil, which can be easily adjusted. The final adjustment has now begun! First loosen the screws on the brake pads until the brake pads are free to move. Press the V-brake arm so that the brake pad and the rim come into direct contact. Be careful not to press too hard. Hold down the V-brake at this time, you can gently tighten the brake pad screws (not too tight), and then repeatedly push the V-brake arm several times to see if the brake pads are in good contact with the surface of the rim. In case of unevenness, the screws of the brake pads are loosened and readjusted until the contact surface is flat. Must be flat, without any gap. This will tighten the brake pad screws. Twist when you pay attention, while the brakes are fixed on one side of the hand, twist the other side of the screw, when the twist does not make the brake pads also move together, here to look good! Twist until you can't move. On the other side, it is also such a tune; if it is well-tuned, how does it feel? ! If you can, now you need to adjust the elastic force of the spring. Everyone looks at the V-brake. There is a small screw in the rotating seat. Twist a twisted screw so that the two sides of it are quite elastic, and when the rim rotates, It's fine to rub against the brake pads; when adjusting, the elastic force should be adjusted slightly. When there is dust or mud stuck on the ring, it will not make a terrible sound. Your brakes are already great now, and the rest is using skills. . . . . . In this way, the adjustment of the V-brake is completed! ! There are some considerations. 1; The brakes are used for a long time, brake pads will leave powder on the rim, so the brake effect is not good, the solution is to use washing powder to clean the rim and brake pads. 2; A good brake line can not put oil, if it is SHIMANO's brake line, you can consider not put oil, if it is not a good effect, then consider putting. Try the brakes again, how about! ! When someone else uses the car in the future, he should be particularly reminded - be careful not to brake! ! Especially before the brake, do not make difficult moves - forward flip! ! I wish you have a good car, a good brake, and then bring you enjoy, good mood! !
