Brake Pads Harley Davidson – Brenta Brake Pads – BR7225

Brenta motorcycle brake pads – sintered PRO compound. This compound is specific for road and track use. The nickel-based mixture allows for excellent performance and resistance to stress. The first bite is more responsive than the sintered Series 4. The friction coefficient is between 0.5 and 0.8. The ideal operating temperature is between 200∞C and 400∞C. This product is ECE R90 approved.

The metal brake pad is sintered metal.

The sintered brake pad gets its name from the process of manufacture, from which it is made. They are mainly made from powdered metal that is placed in a furnace and heated to a temperature below its melting point, 1000°. Pressure is applied, and the metal particles adhere to each other. The finished product is porous and has what I like to call “nooks and crannies.”

This makes them different from organic or resin brake pads, which are made of petroleum composite materials

Metal Brake Pads no need to run in.

The sintered brake pad has the advantage on not needing to be run in, there are ready to use contrarily to organic brake pads, which need deglazing.

Glazing of brake pads is a phenomenon specific to the organic brake pads.

This phenomenon is created, by the reorganisation of the chemical elements that they are made up of. A phenomenon, which, can be avoided by a careful running in to stabilise the corposants of the resin.

Setting up metal against metal 

The running in of a metal brake pad has a very different objective, the phenomenon of glazing doesn’t exist.  In this case, it consists of making sure that the brake pad marries correctly to the disk if the brake disk isn’t new, to make sure there is the maximum contact between the two.  Therefore, during the running in period, the braking will quickly get better obtaining an optimum braking after some tries. 

The heating process, an integral part of the formula

In both organic and metallic brake pads, the petrol products in one case, and the compacted powders in the other, the pad must be fused by heat.  The major difference between these two products are the heating temperatures. An organic brake pad is heated up to temperatures between 200° and 300°, whereas the metal brake pads have to be heated up to temperature around 1000°C.  These high temperatures in the fabrication have a long lasting effect as certain braking can obtain temperatures of more than 200°c.  The organic in this case will degrade quickly as in the metallic is still in its comfort zone.
