What Are Semi Metallic Brake Pads ?
Semi metallic brake pads are one of the most commonly used friction materials in commercial vehicles and heavy-duty trucks. Composed of 30%–65% metal fibers, such as steel, iron, or copper alloys, these brake pads are engineered to deliver strong stopping power and excellent heat dissipation under high-load conditions.
Semi metallic brake pads are widely used in:
- Heavy duty truck brake pads
- 18 wheeler brake pad applications
- Semi trailer brake pads
- Bus brake pad systems
What Are Low Metallic Brake Pads ?
Low metallic brake pads are a type of brake pad that contains less metal content compared to semi metallic pads. They are designed to provide a balance of smooth braking, low noise, and moderate heat resistance.
Second, the low-wear feature indirectly extends the service life of brake discs. Brake pads and brake discs are the “golden partners” of the brake system. The high-hardness particles in low-quality brake pads will accelerate the wear of brake discs, leading to premature scrapping of brake discs (the purchase cost of a set of heavy-duty truck brake discs is about 3-5 times that of brake pads). Tuoba® Brake Pads control the hardness and particle distribution of friction materials through precision molding technology. While ensuring braking force, they minimize the wear on brake discs, which is equivalent to saving enterprises the hidden cost of brake disc replacement.
Key features of low metallic brake pads include:
- Small amounts of steel or copper fibers
- Organic friction materials for quieter operation
- Performance additives to improve braking smoothness
These brake pads are commonly used in:
- Urban buses (bus brake pad)
- Medium-duty trucksVehicles where noise reduction and lower brake dust are priorities
- Low metallic brake pads provide a quieter, cleaner braking experience while maintaining adequate stopping power for standard-duty applications.
Low Metallic vs Semi Metallic Brake Pads — Performance Comparison
When deciding between low metallic vs semi metallic brake pads, understanding the differences in performance is crucial. Below is a detailed comparison:
| Performance Factor | Low Metallic Brake Pads | Semi Metallic Brake Pads | Typical Applications |
| Heat Resistance | Moderate, suitable for city and moderate-load driving | Excellent, suitable for long downhill or heavy-load braking | Heavy duty truck brake pads, 18 wheeler brake pad, semi trailer brake pads |
| Wear Rate | Gentle on rotors, less wear | Higher, can wear rotors faster | Bus and urban vehicles, medium-duty trucks |
| Noise | Quieter braking, less vibration | Can produce brake squeal under some conditions | Bus brake pad, city buses, commercial vehicles |
| Brake Dust | Produces lighter, finer dust | Produces more metallic dust under heavy load | Urban vehicles, commercial fleets |
| Braking Performance | Smooth but slightly lower friction | High friction, strong and consistent stopping power | Heavy duty truck brake pads, 18 wheeler brake pad, semi trailer brake pads |
| High Temperature Performance | Adequate for moderate driving | Excellent, resists thermal degradation | Semi trailer brake pads, long-haul trucks |
| Fade Resistance | Moderate | Excellent under continuous high load | Heavy-duty trucks and trailers |
Which Brake Pad Should You Choose?
Choose semi metallic brake pads if you need:
- Maximum braking force
- High heat resistanc
- Reliable performance for 18 wheeler brake pad, semi trailer brake pads, or heavy duty truck brake pads
Choose low metallic brake pads if you prioritize
- Lower noise and reduced brake dust
- Smooth braking experience
- Applications like bus brake pad or medium-duty vehicles
Both types of brake pads are essential for commercial vehicle safety. Your choice depends on the specific vehicle type and operating conditions.
