BREMBO PADS FEATURES

The compounds that are normally used in brake systems are classified into two families, ORGANIC and SINTERED. The chemistry of the friction material is of course different from manufacturer to manufacturer, you can still describe in principle the composition of the two families of compounds: sintered materials are substantially composed of metal powders, which are not bonded to each other through a process that requires very high pressures and temperatures, precisely called SINTERING.

The desired shape is obtained through a die and there are no adhesives: the sintering process causes the dough to adhere to the metal support (the chip). Moreover, in the initial compound, they are added percentage of lubricants and abrasives. The metal powders determine the coefficient of friction, and that is what restrains the pad, while the lubricants (although talk of lubricants in the brake pad may seem counterintuitive) concur in the stability of braking, that is, allow a constant braking and without “tearing”. The abrasive discs keep clean by removing deposits on the braking surface.

Organic Materials: are mainly composed of resin binders, metals, lubricants and abrasives. In this case the coefficient of friction is generated by metals and by the resins, while lubricants and abrasives performing the work described above.
To briefly summarize we can say that the metal powders (in the sintered) and the most any metal binding resins (in organic) determine in function of their nature and percentage of the degree of the friction coefficient; lubricants perform the function of friction stabilizers and abrasives keep the disc clean.

CHOICE OF COMPOUND
The main reason why it is necessary to make an informed choice, (talking of road pads) leads back to the performance of the value of the friction coefficient of a specific compound as the temperature changes, where 350 ° C. can be considered the dividing line between the temperatures developed in the road rather than on the track above this temperature a street compound will enter fading (lowering dellâ’efficacia brake due to increased disc and pad temperature. In simple words the pad always will brake less and will tend to “slip” on the disc.
Even the type of vehicle contributes strongly in a mixed design: you take as an example the maxi-scooter vehicles for weight, speed and performance have reached the level of the motorcycles. Well their typical use, (city use with continuous braking at low speed and intense use of the rear brake) have led manufacturers of pellets to dedicate a specific study.
The off-road is a symptomatic example: characteristic external agents of this motorcycle specialties (sand, water and mud) must be taken into appropriate consideration to avoid performance decay or high wear.
