Компоненти на производот

The SHIMANO Ultegra 6800 Road Brake Shoe Set includes the following components:

• R55C4 Brake Pads
• Aluminum Pad Holders
• Mounting Hardware (bolts, washers)

Поставување и инсталација

Proper installation is crucial for safe and effective braking. If you are unsure about any step, consult a professional bicycle mechanic.

Потребни алатки

• Hex wrench set (typically 5mm or 6mm for brake caliper bolts)
• Small flat-head screwdriver (for pad retention screws)
• Моментален клуч (препорачан за прецизно затегнување)
• Чиста партал

Чекори за инсталација

1. Отстранете ги старите влошки за сопирачки: Loosen the small retention screw on the brake shoe holder using a flat-head screwdriver. Slide out the old brake pad inserts. If replacing the entire shoe, loosen the main bolt securing the brake shoe to the caliper arm with a hex wrench and remove the old shoe.
2. Clean Brake Calipers: Use a clean rag to wipe away any dirt or debris from the brake caliper arms and the area where the brake shoes attach.
3. Install New Brake Shoes/Pads: If installing new pads into existing holders, slide the new R55C4 pads into the aluminum holders, ensuring the curved surface matches the rim's curvature and the open end faces the rear of the bike. Secure with the retention screw. If installing new complete brake shoes, attach them to the caliper arms using the main bolt, ensuring the correct orientation for left and right sides.
4. Adjust Pad Alignment: Loosen the main bolt slightly, allowing the brake shoe to move. Position the brake pad so it is centered on the rim's braking surface and parallel to the rim. Ensure there is no contact with the tire or spokes.
5. Set Toe-In (Optional but Recommended): For optimal performance and to reduce brake squeal, slightly angle the front of the brake pad inward so it contacts the rim just before the rear of the pad. This can be achieved by placing a thin shim (e.g., a business card) under the rear of the pad while tightening the main bolt.
6. Затегнете ги завртките: Once aligned, firmly tighten the main bolt securing the brake shoe to the caliper arm. If using a torque wrench, refer to your caliper's specifications for the correct torque value. Tighten the pad retention screw if applicable.
7. Тест сопирачки: Squeeze the brake levers several times to ensure the pads seat correctly. Check for firm lever feel and effective stopping power. Re-check alignment after initial use.

Операција

Proper operation of your brake shoes involves understanding their function and ensuring correct adjustment for consistent and reliable braking.

Прилагодување на сопирачките

• Lever Feel: Ensure your brake levers provide a firm and consistent feel. If the levers feel spongy or pull too close to the handlebar, the brake cable tension may need adjustment or the system may require bleeding (for hydraulic brakes, though these are for caliper).
• Pad Contact: The brake pads should make full and even contact with the rim's braking surface when the brake lever is applied. Uneven contact can lead to reduced braking power and premature wear.
• Расчистување: When the brake lever is released, the pads should retract fully, providing adequate clearance between the pads and the rim to prevent rubbing.

Одржување

Regular maintenance extends the life of your brake shoes and ensures consistent braking performance.

• Редовно чистење: Periodically clean the brake pads and rim braking surfaces with a clean cloth to remove dirt, grit, and road grime. Contaminants can reduce braking effectiveness and accelerate wear.
• Проверете дали има абење: Regularly inspect the brake pads for wear. The R55C4 pads have wear indicator grooves. Replace the pads when these grooves are no longer visible or when the pad material is significantly worn.
• Проверете дали има штета: Inspect the aluminum pad holders for any signs of damage, cracks, or bending. Replace any damaged components immediately.
• Затегнатост на сврзувачките елементи: Periodically check that all mounting bolts and retention screws are securely tightened.

Решавање проблеми

Addressing common issues can help maintain optimal braking performance.

• Пискави сопирачки:
  • Причина: Contaminated pads/rim, improper toe-in, loose components.
  • Решение: Clean pads and rim. Re-adjust toe-in. Ensure all bolts are tightened.
• Poor Stopping Power:
  • Причина: Worn pads, contaminated pads/rim, incorrect pad alignment, loose cable tension.
  • Решение: Replace worn pads. Clean pads and rim. Re-align pads. Adjust brake cable tension.
• Нерамномерно носење на влошки:
  • Причина: Improper pad alignment, bent caliper arm.
  • Решение: Re-align pads to ensure full and even contact with the rim. Inspect caliper for damage.
