BREMBO BRAKE PAD COMPOUNDS
The compounds used normally in braking systems are classifiable in just two families, ORGANIC and SINTERED, although the choice of one compound over another is not dependent solely on the type of use: in effect, pads of different type can be used in the same field of application.
+ Sintered materials: these are metallic powders, mixed with lubricants and abrasive agents in such a way as to produce a compound that is solidified by compacting even at high temperatures. The compound is bonded to a metal backing plate of whatever shape as part of the sintering process, with no additional adhesive utilized. The metal powders determine the braking power of the pad at high temperatures. The lubricants help to stabilize the overall braking action, and the abrasives keep the discs clean.
+ Organic materials: these are composed mainly of resin binders, metals, lubricants and abrasives. In this instance the friction coefficient is generated by the metals and the resins, with the lubricants and abrasives performing the functions as mentioned above.
+ Selecting a compound: all brake pads have a typical field of application. This will depend on the different situations a brake pad has to deal with: racing – braking is optimized at high temperatures, road – high stability required, with brakes applied cold and at medium temperatures. Brembo has an answer to every need.
+ Bedding-in: this is a particularly important procedure for all compounds, and crucial for the RC compound. The pads are bedded in by applying the brakes lightly several times and ending with a firm bite, leaving a pause between one squeeze and the next. This will produce the correct heating and cooling cycle needed to prepare the system. The duration of the bedding-in period depends on the type of compound: generally longer for organic compounds than for sintered.
RC – SC These pads have been designed to guarantee their users exceptional performance. Materials of this type are notable mainly for their high friction coefficient and constant efficiency, especially when exposed to high disc temperatures. These characteristics guarantee an excellent and uniform braking action for the full duration of the race, with less likelihood that fading will occur. Pads of this type provide scant efficiency at lower temperature – a factor of limited importance in racing situations – and are therefore not ideal for road use.
RC – Track-only compound. This is a true racing pad, suitable for any kind of competition on the racetrack. With an excellent friction coefficient and – more especially – exceptional stability at high temperatures, the compound gives constant braking lap after lap, from grid to flag.
SC – Sintered compound for track/road use, with high friction coefficient when hot. This is a material that stays very stable in all running conditions, and having a good friction coefficient when cold, the material is also compatible with road use.
SA – Carbon-Ceramic – SP These are characterized by a high friction coefficient that stays constant whatever the operating conditions – in heat and cold alike – as well as resisting wear, for superior durability and better mileage.
SA – A sintered compound intended specifically for front brakes, typified by particularly good efficiency under all operating conditions. An ideal alternative to OE pads.
Carbon-Ceramic – The evolution of the organic compound, featuring a higher carbon content. This friction material offers increased mileage, and good performance in all conditions: heat and cold, wet and dry.
SP – A sintered compound intended specifically for rear brakes, stable in all operating conditions
GENUINE / OEM
Friction material developed by Brembo for OE products and selected by motorcycle manufacturers. Dealers are provided with a catalogue showing the cases where the suggested part-number corresponds exactly to the material used for the specific application. The pads can be of sintered or Carbon Ceramic material.
