A metal–ceramic friction material comprising a very sophisticated bronze-graphite full-metal mixture formulation with uniformly indispersed very fine grade metal friction particles, that is suitable for both dry and wet friction applications.


Metal-ceramic bronze-graphite friction material is an all-metal mixture designed for applications both on dry and wet conditions.
Finer metallic friction additives are spread evenly in the base fine bronze body.
K5 disc pad formulation


  • High static friction coefficient.
  • Good abrasive resistance, and self cleaning capability.
  • High braking power to 500°C. (750°C. in bursts).
  • Low abrasive interaction with the brake rotor material.
  • Three(3) times +/- longer operational life compared to organic and Kevlar composite materials.

„K5” friction material is Lead and Asbestos free.


  • This material was developed for OFF-ROAD races because it features long service life on heavy-duty drive tracks.
    a) hot weather / dry - only rear brake
    b) hard terrain - front and rear brake
  • The sintered materials feature self-cleaning effect.
  • The material may be used on rear brake of road racing motorcycles.


Specific pressure: P < 2.0 Mpa
Sliding velocity: V < 20 m.s-1
Constant maximum temp: 500°C
Short time maximum temp.: 750°C


  • Replacement of brake pads should be done in dry clean conditions, and prefereably by a professionally qualified person. 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. GOLDfren®, because of excellent common friction properties.
