1. انتهى المنتجview
The SHIMANO N04C Disc Brake Pads are high-performance metallic brake pads designed for specific SHIMANO 4-piston hydraulic disc brake systems. These pads feature a sintered metal compound for consistent stopping power in various weather conditions and include finned alloy radiator cooling fins to enhance heat dissipation, reducing brake fade during demanding rides. They are constructed with durable stainless steel back plates for increased lifespan and resistance to wear.

2. محتويات العبوة
Each package of SHIMANO N04C Disc Brake Pads typically includes:
- Disc Brake Pad (quantity as specified on packaging, usually a pair for one caliper)
- Spring (if applicable, for pad retention)
- Split Pin or Cotter Pin (for securing pads in caliper)
3. المميزات
- High-Performance Sintered Metal Compound: Provides reliable, consistent stopping power in varied weather conditions (wet and dry).
- Finned Alloy Radiator Cooling Fins: Enhances heat dissipation, reducing brake fade during long descents and aggressive riding.
- بناء متين: Stainless steel back plates and finned alloy components ensure increased lifespan and resistance to heat and wear.
- Optimized for Aggressive Riding: Designed for demanding trail use, offering exceptional stopping performance and heat management.
4. التوافق
These SHIMANO N04C Disc Brake Pads are compatible with the following SHIMANO 4-piston brake systems:
- SHIMANO M9120 (XTR)
- SHIMANO M8120 (XT)
- SHIMANO M7120 (SLX)
Ensure your brake caliper model matches one of the listed compatible systems before installation.
5. معلومات السلامة
Always prioritize safety when working on bicycle brakes. Improper installation or maintenance can lead to serious injury or death. If you are unsure about any step, consult a professional bicycle mechanic.
- ارتدِ معدات السلامة المناسبة، بما في ذلك حماية العين.
- Ensure the bicycle is stable and secure before beginning work.
- Avoid touching the braking surface of the pads or rotors with bare hands to prevent contamination.
- Do not use contaminated brake pads or rotors. Contamination can severely reduce braking performance.
- After installation, always test the brakes thoroughly in a safe area before riding.
6. دليل التثبيت
This guide provides general steps for replacing disc brake pads. Specific procedures may vary slightly depending on your brake model. Refer to your brake caliper's specific service manual for detailed instructions.
- تجهيز الدراجة: Secure the bicycle in a repair stand. Remove the wheel from the frame.
- إزالة الوسادات القديمة:
- Locate the pad retention pin (often secured by a split pin or screw). Remove the split pin (if present) and then the main retention pin.
- Carefully pull the old brake pads out of the caliper. Note their orientation.
- نظف الفرجار: Use a clean cloth and isopropyl alcohol to clean the inside of the brake caliper, removing any dust or residue. Do not use brake cleaner or other harsh chemicals that could damage seals.
- إعادة ضبط المكابس: Gently push the brake caliper pistons back into their bores using a plastic tire lever or a dedicated piston press tool. This creates space for the new, thicker pads. Be careful not to damage the pistons or seals.
- تثبيت الوسادات الجديدة:
- Insert the new SHIMANO N04C brake pads into the caliper, ensuring the spring (if included) is correctly positioned between them. The metallic braking surface should face the rotor.
- Align the holes in the pads and spring with the retention pin holes in the caliper.
- Reinsert the retention pin through the pads and caliper. Secure it with the split pin or tighten the screw.
- Reinstall Wheel and Align Caliper: Reinstall the wheel. Loosen the caliper mounting bolts slightly. Squeeze the brake lever firmly several times to center the caliper over the rotor. While holding the brake lever, tighten the caliper mounting bolts.
- Bed-In New Pads: New brake pads require a "bedding-in" process to achieve full performance. Perform several moderate stops from increasing speeds (e.g., 10-15 mph, then 20-25 mph) without coming to a complete stop. This transfers pad material to the rotor, optimizing friction. Avoid hard braking or prolonged dragging of the brakes during this process.
7. Operation and Braking Technique
Proper braking technique is crucial for safety and performance. Disc brakes offer powerful stopping, but modulation is key.
- تعديل: Apply brake pressure gradually. Avoid sudden, hard braking unless in an emergency.
- Front vs. Rear: The front brake provides most of the stopping power. Use both brakes simultaneously, with slightly more emphasis on the front, for effective and controlled deceleration.
- الظروف الرطبة: Metallic pads perform well in wet conditions, but braking distance may still increase. Apply brakes earlier and more gently.
- Long Descents: For long descents, alternate between front and rear brakes, and apply them in short bursts rather than dragging them continuously. This helps manage heat and prevents brake fade.
8. الصيانة
Regular inspection and maintenance will ensure optimal performance and longevity of your SHIMANO N04C Disc Brake Pads.
- Pad Wear Inspection: Regularly check the thickness of the brake pad material. Replace pads when the friction material is worn down to approximately 0.5mm or less, or if the backing plate is close to touching the rotor.
- فحص الدوار: Inspect brake rotors for wear, damage, or contamination. Replace rotors if they are bent, excessively worn, or deeply scored.
- تنظيف: Keep brake pads and rotors clean. If contamination (oil, grease) occurs, replace the pads and clean the rotor thoroughly with isopropyl alcohol.
- سائل الفرامل: Ensure your hydraulic brake system has adequate and clean brake fluid. Refer to your brake system's manual for fluid maintenance.
9. استكشاف الأخطاء وإصلاحها
Common issues related to disc brake pads and potential solutions:
| الأعراض | السبب المحتمل | حل |
|---|---|---|
| Squealing/Noise | Contaminated pads/rotor, misaligned caliper, worn pads, loose bolts. | Clean rotor with isopropyl alcohol, replace pads if contaminated, realign caliper, check bolt tightness, replace worn pads. |
| قوة الكبح المنخفضة | Worn pads, contaminated pads/rotor, air in hydraulic system, brake fade (overheating). | Replace worn/contaminated pads, bleed hydraulic system (professional recommended), allow brakes to cool. |
| تآكل غير متساوٍ للفوط الصحية | Misaligned caliper, sticky piston. | Realign caliper, clean and lubricate pistons (professional recommended). |
If troubleshooting steps do not resolve the issue, consult a qualified bicycle mechanic.
