Bull Chemicals’ brake pads Ceramic Fiber is mainly alumina-silica type, brake pads mixture with 45%-55% alumina, 40%-50% silica, 3-8μm diameter and 2-10mm length—key for stable performance.

First: Enhancing Structural Stability
Brake pads face 400-600°C in normal braking and over 800°C in emergencies. Our ceramic fiber’s melting point exceeds 1700°C, retaining integrity. Mixed with binders, it forms a rigid network. Tests show pads with 15%-20% of our fiber have <5% deformation after 10,000 high-temperature cycles, vs. 12%-15% without, preventing warping.
Second: Optimizing Friction Performance
It maintains a 0.35-0.45 friction coefficient between 100°C-700°C, with only ±0.03 fluctuation—far lower than metal fibers’ ±0.1. This avoids brake fade or grabbing. Tests confirm a 36.2m stopping distance from 100km/h, 2.1m shorter than traditional fibers.
Third: Reducing Wear
With Mohs hardness 5-6 (lower than brake discs’ 7-8), it won’t scratch discs. Pads with our fiber last 40,000-50,000km—20%-30% longer than asbestos/steel fiber ones. Disc wear drops 15%-20%, cutting maintenance costs.
Fourth: Enabling Quieter and Cleaner Operation
Its porous structure absorbs noise, keeping braking sound below 65dB. Chemically stable, it produces no heavy metal dust, complying with EU REACH.
Bull Chemicals enforces strict quality checks. Each batch passes tests, and our fiber is trusted by leading brake suppliers. It’s a core component—choose us for safer, durable, eco-friendly brake pads .
