1. Core Material Difference
- Copper semi-metallic pads (VXM type) Made of copper fiber mixed with organic resin by compression molding (semi-metallic formula). Resin takes up a large proportion, with copper fiber added to boost wear resistance.
- Full sintered metal pads (MOTSUV type) Formed by high-temperature & high-pressure sintering of pure copper powder plus other metallic powders; fully metallic composition with zero resin content.
2. Performance Comparison Table
表格
| Comparison Item | Copper Semi-metallic Pads | Full Sintered Metal Pads |
|---|---|---|
| Noise Performance | ★★★★★Resin absorbs vibration for quiet braking, ideal for urban riding | ★★Metallic friction causes minor squeal during low-speed light braking |
| Heat Resistance & Anti-fade | ★★★Prone to heat softening and power drop on long downhill with continuous braking | ★★★★★Excellent heat conductivity, no brake fade under aggressive downhill/enduro riding |
| Wear Service Life | ★★★Double the lifespan of pure resin pads; replacement needed after 10,000~20,000km daily use | ★★★★★3~5 times longer service life than semi-metallic; superior performance in muddy/sandy harsh terrain |
| Rotor Wear Level | ★★★★★Soft compound barely scratches brake rotors | ★★★High hardness causes slight gradual rotor abrasion over long-term use |
| Wet Weather Performance | ★★★★Slight braking power loss when soaked | ★★★★★Full-metal structure unaffected by rain/mud, stable stopping on wet trails |
| Cost | Budget-friendly, low replacement cost | Higher upfront cost but fewer replacements over time |
3. Scenario-based Buying Advice
Choose Copper Semi-metallic Brake Pads if:
- Daily city commuting on paved roads, prioritizing quiet braking and original rotor protection
- Casual short-distance outdoor rides with rare long steep downhill sections
- Limited budget, balancing durability and low noise
Choose Full Sintered Metal Brake Pads if:
- Mountain off-road, long climbing & downhill, enduro/downhill biking with frequent heavy braking
- Regular riding in rainy, muddy or rugged terrain, or heavy-load hauling
- Prioritize extreme braking performance and long service life over minor brake squeal
4. Practical Tips 💡
- Mixed setup solution: Install sintered pads on front wheel (main load for heat resistance) + semi-metallic pads on rear wheel (noise reduction for daily comfort).
- Use copper semi-metallic pads for stock original rotors to avoid premature rotor thinning; switch to full sintered pads after upgrading to reinforced thickened rotors.
