Abrasive substances of the 'organic' category consist of fibres, which can be gained from glass, rubber, carbon or Kevlar® and Twaron®. Furthermore, they consist of fillers and temperature-resistant synthetic or natural resin. These coverings are said to be softer, quieter, but they also have the reputation of fast wear and brake dust development. On top of that, especially after increased temperature levels, they develop a worse reaming performance. They are designed for the hobby and entry-level field.Features:- Soft mix, minimizes disturbing noise generation on vulnerable brake systems.- Brake force builds up more slowly.- Ideally suitable for the hobby and entry-level field.- Faster wear than with sintered coating.
