Metal-ceramic, typical iron friction material designed for both dry and wet friction. Finer additives compared with K1 material are added to the base iron compound.

AD friction material is Lead and Asbestos free.

AD disc pad formulation


  • High static friction coefficient.
  • Good abrasive resistance.
  • High braking power to 500C.
  • very good binding strength between copper lined steel base plate and friction layer
  • wearing rate by 20 % lower comparing with competitive sintered products of its category for common use
  • Low abrasive interaction with the brake rotor material.
  • Three(3) times +/- longer operational life compared to organic and Kevlar composite Materials.

Range of Application

  • the material is suitable for dry and wet conditions for road/and off-road motorcycles; in road motorcycle application suited both for front/and rear brake while for off-roads we are recommending to use it for front brake
  • The material is designed for common road riding application.


Specific pressure: P < 5.0 Mpa
Sliding speed: V < 40 m.s-1
Constant maximum temp.: 450C
Short time maximum temp.: 700C


  • 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.
