Metal-ceramic friction material designed for friction on dry and wet conditions is produced applying advanced powder metallurgy method, which is a leader on sintered process field. Metal-ceramic material, K1, is a bronze-graphite friction material designed for wet friction applications. Coarser non-metallic friction additives are spread evenly in the base fine bronze body.
K1 disc pad formulation

It suits for off-road motorcycles of a high service life in heavy duty drive surface conditions, e.g. sand, mud.

  • for a period of higher temperatures we are recommending to substitute it by K5 material
  • on muddy conditions, it has a self-cleaning effect
  • suitable for rear brake lining
  • we are not recommending to use it for the front brake installed on road motorcycles, as well as off-road types


  • High static friction coefficient.
  • High abrasive resistance.
  • High braking power to 450°C. (Max. 750°C.)
  • Low abrasive interaction with the brake rotor material.
  • Three(3) times +/- longer operational life compared to organic and Kevlar composite materials.


Specific pressure: P < 3.5 Mpa
Sliding speed: V < 45 m.s-1
Constant maximum temp.: 450°C
Short time maximum temp.: 800°C


  • Replacement of brake pads should be done in dry clean conditions.
  • If the friction material Comes into contact with oil or brake fluid and the liquid soaks into the pores of the friction Material, a catastrophic fall in friction coefficient (braking performance) could occur.
  • Braking performance is significantly influenced by the quality of the braking surface of the Disc rotor, by the age and quality of the brake fluid, and by the correct choice of Complementary friction pad material.
  • To achieve perfect brake effects we are recommending to use also brake wheels and hoses of the same brand as that of brake lining, i.e. GOLDfrenŽ, because of excellent common friction properties
