- Test brakes thoroughly before riding.
3. 설정 및 설치
This section outlines the general steps for installing the SHIMANO Exustar BR-T4000 Rear V-Brake. Specific bicycle frame designs may require slight variations.
- 프레임을 준비하세요: Ensure the brake bosses on your bicycle frame are clean and free of debris. Apply a thin layer of grease to the brake bosses.
- Install Brake Arms: Slide each brake arm onto its respective brake boss. Secure the brake arms with the provided bolts. Do not overtighten initially, as adjustments will be needed.
- Attach Brake Pads: Install the brake pads onto the brake arms. Ensure the pads are oriented correctly for your wheel's rotation and that the curved surface faces the rim. The brake pads should be positioned to contact the rim squarely when the brake is applied.
- Connect Brake Cable:
- Route the brake cable from the brake lever through the cable housing.
- Insert the brake noodle (cable guide) into the designated slot on one brake arm.
- Pass the brake cable through the cable clamp on the opposite brake arm.
- Pull the cable taut, ensuring the brake pads are close to the rim but not touching. Secure the cable with the cable clamp 볼트.
- Center the Brakes: Use the spring tension adjustment screws on each brake arm to center the brake pads relative to the rim. The pads should be equidistant from the rim when the brake is not applied.
- Adjust Brake Pad Angle and Distance:
- Loosen the brake pad mounting bolts.
- Adjust the pads so they contact the rim fully and evenly when the brake lever is squeezed.
- Ensure the pads do not touch the tire or spokes.
- Tighten the brake pad mounting bolts securely.
- Final Cable Tension Adjustment: Fine-tune the brake cable tension using the barrel adjuster on your brake lever or the cable clamp bolt on the brake arm. The brake lever should have a firm feel and stop the wheel effectively without bottoming out against the handlebar.

4. 사용 설명서
The SHIMANO Exustar BR-T4000 V-Brake operates by squeezing the brake lever, which pulls the brake cable, causing the brake arms to pivot and the pads to press against the wheel rim, slowing or stopping the bicycle.
- 제동 기술: Apply brake levers smoothly and progressively. Avoid sudden, hard braking, especially with the rear brake, as this can cause skidding and loss of control.
- 습한 조건: In wet conditions, braking performance may be reduced. Apply brakes earlier and with more force than in dry conditions.
- Inspection Before Each Ride: Before each ride, check that both brake levers operate smoothly and that the brake pads make full contact with the rim. Ensure the brake cable is not frayed and that the brake arms return to their open position freely.
5. 유지관리
Regular maintenance ensures optimal performance and extends the lifespan of your SHIMANO V-Brakes.
- 브레이크 패드 마모: Inspect brake pads regularly for wear. Replace pads when the wear indicators are no longer visible or if the pads become hardened or contaminated.
- Rim Cleaning: Keep wheel rims clean and free of grease, oil, and dirt to ensure effective braking.
- 케이블 및 하우징: Check brake cables and housing for kinks, fraying, or corrosion. Replace them if any damage is observed to maintain smooth brake operation.
- Pivot Points: Periodically lubricate the pivot points of the brake arms with a light grease to ensure smooth movement.
- 볼트 조임: Regularly check all mounting bolts for proper tightness.
6. 문제 해결
| 문제 | 가능한 원인 | 해결책 |
|---|---|---|
| 브레이크가 푹신하거나 힘이 약한 느낌이 듭니다. | Loose cable, worn pads, contaminated rim. | Tighten cable, replace pads, clean rim. |
| Brakes squeal loudly. | Contaminated pads/rim, incorrect pad angle (toe-in), loose components. | Clean pads/rim, adjust pad angle, check bolt tightness. |
| Brake pads rub the rim continuously. | Brakes not centered, spring tension imbalance, bent brake arm. | Adjust centering screws, check spring tension, inspect for damage. |
| Brake lever pulls to the handlebar. | Excessive cable slack, severely worn pads. | Adjust cable tension, replace pads. |
