MTB brake pads for HOPE M4

19.95 x 27.8 x 4.3

the set contains 4 pcs

DS universal mixture - sintered metal-ceramic friction material is a co-metallic mixture that is intended for friction in both dry and wet conditions. Finer metal friction additives are evenly distributed in the basic fine bronze frame. This is a lead-free and asbestos-free material.

- the material was developed for racing purposes, as it is characterized by high durability in difficult terrain

- is suitable for dry and wet extreme conditions

- these sintered materials are characterized by a self-cleaning effect

- a high static coefficient of friction in the entire range of operating conditions

- constancy of the force of the braking effect throughout the braking period

- high heat resistance up to 600 °C

- perfect braking effect even in extreme conditions (water, mud, sand)

- for all these brakes (Shimano, Hayes, Magura, Avid.....)

- environmental friendliness

specific pressure P<5.0 MPa

sliding speed V<20m/s

permanent temperature 480 °C

short-term max. temperature 600 °C

counter surface of the stainless steel disc

- 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.
