Modified floating ball

Home » Products » Modified floating ball

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:

  1. Improve friction performance and wear.
  2. Increase porosity.
  3. Reduce density.
  4. Reduce brake noise and judder.
