FOIRE AUX QUESTIONS - BR-IM86-F SHIMANO

Quel est le poids maximum supporté par le frein BR-IM86-F ?

Le frein est conçu pour un poids total (vélo + cycliste) jusqu'à 130 kg.

Quels leviers sont compatibles avec ce frein ?

Les leviers recommandés sont : SB-8S20, ST-8S20, SB-7S45, BL-IM60, BL-IM65, BL-IM45. Attention : ces leviers doivent être en position C.R. (mode Cantilever/Roller).

Comment installer le câble de frein sur le BR-IM86-F ?

Suivez les étapes : 1) Insérez le porte-gaine dans le câble intérieur. 2) Passez le câble dans le trou du boulon de fixation côté marque 'F'. 3) Serrez l'écrou. 4) Alignez le repère rouge de la rondelle avec la rainure du poupée. 5) Engagez le câble dans la rainure et accrochez-le au crochet. 6) Insérez le porte-gaine dans le trou du bras de frein et fixez l'embout. 7) Serrez le boulon de réglage pour tendre le câble.

Comment régler le jeu du levier de frein ?

Après avoir rodé le câble en pompant le levier 10 fois, tournez le boulon de réglage pour obtenir environ 15 mm de jeu au levier (distance avant que la force ne devienne soudaine).

Que faire si le frein émet un bruit anormal ?

Un bruit anormal peut indiquer un manque de graisse. Arrêtez immédiatement, retirez le bouchon de graissage et injectez environ 5 g de graisse spéciale pour frein à tambour en tournant lentement la roue. Si le problème persiste, consultez un revendeur.

Puis utiliser le frein BR-IM86-F avec une roue de taille inférieure à 26 pouces ?

Non, l'installation est recommandée uniquement pour des vélos avec roues de 26 pouces ou plus. Sur des roues plus petites, la force de freinage pourrait être excessive et causer un accident.

Comment éviter la surchauffe du frein en descente ?

Évitez un freinage continu prolongé ; alternez frein avant et arrière. La surchauffe peut affaiblir le freinage et réduire la graisse interne.

Quelle est la maintenance périodique recommandée ?

Vérifiez régulièrement le jeu du câble (15 mm), l'état du câble (remplacer si rouillé), le serrage des fixations, et la présence de bruits anormaux. Une graisse tous les 5 000 km ou selon l'usage.

Puis-je démonter l'unité de frein avant pour la nettoyer ?

Non, l'unité avant BR-IM86-F ne doit jamais être démontée. Le démontage entraînerait un dysfonctionnement irréversible.

MODE D'EMPLOI BR-IM86-F SHIMANO

General Safety Information

WARNING

- To avoid serious injuries:

• It is important to completely understand the operation of your bicycle's brake system. Improper use of your bicycle's brake system may result in a loss of control or an accident, which could lead to severe injury. Because each bicycle may handle differently, be sure to learn the proper braking technique (including brake lever pressure and bicycle control characteristics) and operation of your bicycle.
  This can be done by consulting your professional bicycle dealer and the bicycle's owners manual, and by practicing your riding and braking technique.
• If the front brake is applied too strongly, the wheel may lock and the bicycle may fall forward, and serious injury may result.
• The hub of the Shimano front Inter-M brake has a built-in power modulator. This system controls the braking force so that excessive force is not applied if the braking force reaches the specified value. If the hub is not equipped with the power modulator, the braking force may be excessively applied. For this reason, we recommend using the Shimano front Inter-M brake and the hub as a set. Noise is generated by the operation of the power modulator when the brake is applied, but this is not a sign of a malfunction.
• If using the BR-IM86-F/BR-IM85-F in combination with a suspension fork, care must be taken when selecting the suspension fork to use. Please consult with the shop or the bicycle manufacturer. If an incorrect type of suspension fork is selected, it could prevent the suspension fork from functioning properly because of overheating during braking or lack of strength in the fork, which could result in an accident.
• The SB-8S20/ST-8S20/SB-7S45/BL-IM60/BL-IM65/ BL-IM45 brake levers are equipped with a mode switching mechanism. Be sure to use the BR-IM86-F, BR-IM85-F with the mechanism in the C.R. mode position.

C.R mode position

The C indicates the mode position for compatibility with cantilever brakes. The R indicates the mode position for compatibility with roller brakes.

• Obtain and read the service instructions carefully prior to installing the parts. Loose, worn, or damaged parts may cause serious injury to the rider. We strongly recommend only using genuine Shimano replacement parts.
  Always make sure that the front and rear brakes are working correctly before you ride the bicycle.
• If the road surface is wet, the tires will skid more easily. If the tires skid, you may fall off the bicycle. To avoid this, reduce your speed and apply the brakes early and gently
• Read these Technical Service Instructions carefully, and keep them in a safe place for later reference.

CAUTION

- To avoid serious injuries:

1. When using the Shimano Inter-M brake system, avoid continuous application of the brakes when riding down long slopes, as this will cause the internal brake parts to become very hot, and this may weaken braking performance. It may also cause a reduction in the amount of brake grease inside the brake, and this can lead to problems such as abnormally sudden braking. The design of the Shimano Inter-M brake system has been carried out based on standards such as ISO 4210 and DIN 79100-2. These standards specify the performance for an overall weight of 100kg . However, BR-IM86-F is designed with the overall weight assumed to be 130kg . If the overall weight exceeds 100kg (130kg for BR-IM86-F), the braking force provided by the system may be insufficient for correct braking, and durability of the system may also be reduced.
2. The front Inter-M brake system should only be installed to the left side of a bicycle which is 26^ or larger. If it is used on a bicycle which is smaller than 26^ , the braking force may be too great, which could cause accidents.
3. In order to get the best performance from the Shimano front Inter-M brake, be sure to use Shimano brakes cables and brake levers as a set. (Refer to the product line-up.) The amount of movement of the inner cable must be 14.5 mm or more when the brake lever is depressed. If it is less than 14.5 mm, braking performance will suffer, and the brakes may fail to work.

4. Check that the front brake unit is firmly secured to the hub with the brake unit fixing nut.

5. Check that the hub axle is touching the back of the fork end and the wheel is firmly secured to the frame with the quick release or the hub nut. If the wheel is not installed properly, it may come off the frame, which could result in a serious accident when riding.

6. If any of the following occur while using the brakes, stop riding immediately and ask the place of purchase to carry out inspection and repairs.

1) If abnormal noise is heard when the brakes are applied
2) If braking force is abnormally strong
3) If braking force is abnormally weak

In the case of 1) and 2), the cause might be not enough brake grease, so ask the place of purchase to grease the mechanism with special roller brake grease. Before applying grease, remove the grease hole cap and press-fit the tube into the back of the hole. Apply an appropriate amount of grease (approx. 5g) while turning the wheel slowly. After application, check that braking is properly applied and that no abnormal noise is heard.

1. If the brakes are used frequently, the components around the brake may become hot. Do not touch the components for at least 30 minutes after you finish riding the bicycle.

Components around the brake

1. If the brake cable becomes rusted, braking performance will suffer. If this happens, replace the brake cable with a genuine Shimano brake cable and re-check the braking performance.
2. The BR-IM86-F/BR-IM85-F front brake units, and HB-IM70, DH-2R35-E-H/DH-3R35-H front hub units should never be disassembled. If they are disassembled, it will no longer work properly.

NOTE:

• Use a wheel with 3x or 4x spoke lacing. Wheels with radial lacing cannot be used because the spokes and the wheel can be damaged when applying the brakes and brake noise can be generated.
• The front Inter-M brake is different from conventional band brakes in that the inside of the brake drum is filled with grease. This may cause the turning of the wheel to be slightly heavier than usual, particularly in cold weather.

• If you apply the front Inter-M brake strongly while the bicycle is stopped and then shake the wheel, you will notice that there is a small amount of play in the brakes. This is normal, and will not cause any problems at all while riding.

• To check the amount of looseness in the head parts, grasp the middle of the handlebar and one of the front forks as shown in the illustration, and then move the head parts back and forth in the directions indicated by the arrows. Moreover, because the brakes give a small amount of play if you apply the brakes fully and shake the wheel as described above, this will make it more difficult to check the looseness in the head parts.

• Parts are not guaranteed against natural wear or deterioration resulting from normal use.
• For maximum performance we highly recommend Shimano lubricants and maintenance products.
• For any questions regarding methods of handling or adjustment, please contact the place of purchase.
