Key Advantages
- Low Noise & Vibration
- The Brake Pads Mixes combine rubber particles, Kevlar fibers, and ceramic additives, reducing squeal noise by 50% compared to semi-metallic formulas.
- Reduced Rotor Wear
- Non-abrasive brake pads friction materials decrease rotor wear rates by 30%, extending service intervals for heavy vehicles.
- Environmentally Safe
- Asbestos-free composition meets EU Regulation 1907/2006 (REACH) and US EPA standards, eliminating hazardous dust emissions.
- Consistent Performance
- Stable friction coefficient across temperature ranges (-30°C to 550°C), preventing brake fade during prolonged downhill braking.
Storage & Packaging Requirements
- Packaging:
- Individually wrapped in anti-corrosion coated paper.
- Stacked on reinforced pallets (max 20 layers) with edge protectors.
- Storage:
- Temperature: 5°C–35°C in low-humidity environments (<65% RH).
- Avoid direct sunlight and chemical exposure.
Formula Composition Breakdown
The brake pads formula includes:
- Friction Modifiers: Cashew particles (10–15%), graphite (8–12%)
- Binders: Modified phenolic resin (15–18%)
- Reinforcements: Glass fibers (20–25%), aramid pulp (5–8%)
This optimized brake pads mixture ensures durability for trucks under extreme loads while maintaining eco-compliance.
