MATERIAL GP4

Characteristics

A sophisticated metal-ceramic formulation for racing use, GP5 material is produced by ‚,Progressive Powder Technology‘‘-a leader in the field of sintered technologies.

This compound material has been specially formulated for racing use.

GP4 disc pad formulation

Material GP4:

  • racing pads intended for sport applications and for experienced drivers;
  • an advantage is a very low control force to be applied onto the brake pedal;
  • high brake efficiency at maximum speeds;
  • sensitive in the entire speed range;
  • no wear of brake wheels and segments;
  • no brake fluid boiling;
  • not recommended for rear axles of cars not provided with brake effect divider.

FEATURES:

  • Very high static friction coefficient
  • Low abrasive interaction with the brake rotor material Specially modification braking surface
  • Minimal difference between wet and dry braking performance
  • Good abrasive resistance
  • High braking power to 550°C(max.800°C)
  • The sintered friction material is soldered to the copper coated backing plate, so separation (which can happen with organics material) is virtually eliminated as a failure risk.
  • Continuous braking effect

Material operting parametres:

Specific pressure:……………….p <5,0 Mpa
Sliding speed:…………………...V< 30 m/s
Constant maximum temp.:……...550°C
Short time maximum temp.:…….800°C

NOTES:

  • replacement of brake pads shoul be done in dry clean conditions. If the friction material comes into contact with oil or brake fluid and the liquit 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 quantity of the braking surface of the Disc rotor, by the age and quantity of th brake fluid, and by the correct choice of Complementary friction pad material.
