Brake Pads GF 825 AD MTB HOPE (without spring, spring, leaks)

MTB brake pads for HOPE M4

19.95 x 27.8 x 4.3

the set contains 4 pcs

AD material - metal-ceramic friction material designed for dry and wet friction, produced by a progressive method of powder metallurgy, which is becoming a leader in the field of sintered technologies. It is a lead-free and asbestos-free material.

- the material is suitable for dry and wet extreme conditions

- this material is recommended for MTB use

- high static coefficient of friction

- good abrasion resistance

- great braking ability at temperatures up to 480 °C

- a very good connection between the copper-plated steel pad and the friction layer

- very low impact on the brake disc

- three times the lifespan of the plates compared to competing organic linings

- 20% less wear than competing sintered products

- immediate braking effect when wet

specific pressure P<3.0 MPa

sliding speed V<40m/s

permanent temperature 480 °C

short-term max. temperature 600 °C

counter surface steel

- we recommend replacing these brake pads in specialized service centers

- ATTENTION protect these materials from contact with oils, as they may soak into the pores, which could cause a decrease in the coefficient of friction.

- the test conditions affect the value of the friction coefficient of specific wear and temperature.

ATTENTION - the braking effects are greatly influenced by various circumstances:

- the condition and age of the brake fluid, the quality of the material and the condition of the brake disc and the correct choice of material for a suitable braking effect.

The Goldfren company has been on the world market in the field of brake parts since 1991. During its existence, it has become one of the largest manufacturers. In recent years, it has managed to expand the production line of sintered brake linings from the motorcycle industry to brake linings for aircraft, cranes, mountain bikes, sidecars and motor sports, thanks to the development of new materials, tests and trials. For more than 8 years, the company Gold fren has been engaged in the production of sintered brake linings for bicycles. Brake pads are produced in two materials for normal operation AD and DS and one material for racing purposes under the name SW33 was developed this year in cooperation with the TEAM TOYOTA DOLÁK MTB racing team under the leadership of Mr. Jan Hruška

The company still intensively continues development based on individual customer requirements in order to satisfy them as much as possible and be competitive in the world.

Brake plates are characterized by a high and constant friction coefficient up to temperatures of 800°C and thermal stability with minimal abrasion. The materials do not contain asbestos, glass fibers, formaldehyde and are environmentally friendly. Compared to organic friction materials, they have a several times longer service life.
