Modified floating ball is made from hollow fillers floating on water after chemically treatment, dry and screening. It is applicable for disc pad and brake lining.
Product advantages include:
- Improve friction performance and wear.
- Increase porosity.
- Reduce density.
- Reduce brake noise and judder.
