Introduction to Truck Brake Pads with Brass-Free Formula
Brass-free truck brake pads employ an innovative Brake Pads Formula that replaces traditional copper components with eco-friendly alternatives, complying with global regulations (e.g., California SB-346). This Brake Pads Mixture combines advanced Brake Pads Friction Materials to deliver robust performance under heavy-duty conditions.

Advantages of Brass-Free Brake Pads
- Eco-Compliance & Reduced Corrosion
- Eliminates copper and brass in the Brake Pads Mixes, meeting EU Regulation No 2023/1711 and US EPA standards.
- Reduces wheel hub corrosion by 60% compared to conventional formulas.
- Enhanced Durability
- The brake pads friction materials blend ceramic fibers (25%), aramid particles (15%), and graphite (10%) to withstand high axial loads (up to 12 tons).
- Stable Friction Performance
- Maintains a friction coefficient variance <5% across wet/dry conditions, critical for truck safety.
- Low Noise & Dust
- Noise levels <75 dB at 80 km/h braking, with dust emission reduced by 40% through optimized brake pads formula.
Storage & Packaging Guidelines
- Packaging:
- Sealed in vacuum-coated aluminum bags with desiccant packs.
- Reinforced cartons (burst strength ≥200 kPa) or wooden crates for bulk shipments.
- Storage:
- Temperature: 5°C–30°C, relative humidity <65%.
- Stacking limit: ≤8 layers to prevent material deformation.
Key Components of the Formula
The brass-free brake pads mixture includes:
- Friction Modifiers: Steel fibers (18–22%), vermiculite (8%)
- Reinforcements: Basalt fibers (12%), alumina (5%)
- Binders: Modified phenolic resin (10–12%)
This formulation ensures compliance with EURO VII emission standards while enhancing braking efficiency for commercial trucks and trailers.
