Brake pads GF 831 SW MTB Hayes (no spring, spring, leaks)

MTB brake pads for HAYES MX 2/Sole

20.5 x 28.55 x 4

SW33 - mixture for downhill - sintered metal-ceramic friction material 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 would be developed for special sports and racing purposes and is recommended for racing use. Nevertheless, it can also be used for demanding recreational clientele

- is suitable for dry and wet extreme conditions

- uniformly the highest friction coefficient

- good abrasion resistance

- low difference between wet and dry friction

- low effect on the steel counter surface (low wear of the brake disc) - it is a non-aggressive material

- high heat resistance

- extended life compared to organic mixtures

- copper-plated base plate against corrosion

- environmental friendliness

- immediate braking effect in the wet

specific pressure P<3.0 MPa

glide speed V<45m/s

permanent temperature 600 °C

short-term max. temperature 800 °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.
