Historically, brake rotors have always been made in cast iron, and to this day the majority of cars on the road uses this material, aside from exclusive supercars that use carbon ceramic materials instead. Many people are unaware however that the term cast iron includes several types of variants which differ in their chemical composition, and hence their performance.
 

Brembo uses more than 40 different variants of cast iron, in fact. The choice of Original Equipment components in fact exactly mirrors the original equipment material. The same correspondence is not guaranteed by standard components.

The range of Brembo brake pads guarantees maximum braking safety, thanks to the absolute control of all phases of the production process: from research and development to testing, including the friction compound production and the mechanical machining.
 

For its brake pads, Brembo uses more than 100 different compounds, designed to offer the most suitable solution for each type of car and driving style, in terms of both performance and comfort. Imagining such a variety for a Matching Quality manufacturer is simply utopia.

At first glance, a brake rotor with economy quality may appear similar to an Original Equipment product, but who can guarantee that the two will still be aesthetically indistinguishable a few months down the line? There is no guarantee that the effect of a coat of paint will last once it is fitted on a car.
 

Brembo brake rotors with UV paint treatment guarantee superior corrosion resistance, as confirmed by both salt mist spray tests as well as moisture resistance tests. This not only makes for an attractive product for the car user, but it also translates to greater protection for the brake rotor itself against corrosion and atmospheric agents.

Brembo works closely with car manufacturers during the concept of new models, starting with the prototyping phase, in order to approve the most effective braking system. The study of braking components, including static and road tests, is optimised for the car model they will be equipping.
 

Indeed, this particular partnership allows Brembo to find out and therefore replicate the narrow tolerance values envisaged for original equipment braking components, which vary from one system to the next. The same cannot be said for standard component manufacturers, where common drawbacks include brake thickness variations (DTV) and rotor oscillation during revolution, and hence run-out.

Once upon a time, all you needed to do was to take a look at the surface and finish to identify a good brake rotor. Modern brake rotors are much more complex than one might think, thanks to the ventilation chambers inside, to dissipate the heat as quickly as possible, and which cannot be seen unless to cut the rotor open.
 

Several Original Equipment rotors are distinguished by pillar ventilation (PVT) patented by Brembo. This technology, owing to the shape and distribution of the pillars, creates air circulation inside the ventilation chamber, which allows for greater heat removal, as well as generating a barrier against the formation of cracks On Brembo’s latest-generation brake rotors, the pillars have a different geometry and are arranged along three rings along the braking surface. Since they are not entitled to, Matching Quality manufacturers cannot use PVT ventilation.

Brembo brake pads undergo a surface thermal treatment, referred to as scorching, which guarantees maximum efficiency even at the highest temperatures.
 

Usually not present on economy quality brake pads, scorching is designed to eliminate any gases in advance, which could cause a significant reduction in the friction coefficient between the brake rotor and pad at high temperatures. This means there is no fading, and the braking behaviour is constant.

In addition to guaranteeing optimum braking, Brembo Original Equipment brake pads ensure superior levels of comfort during braking. They achieve this thanks to the multiple layers making up the shim, in other words the sequence of rubber, steel and rubber that dampens. However, the fundamental choice, in this case just as for the performance, concerns the compound, which not only ensures safe braking but also has to guarantee maximum comfort and the absence of tiresome noises and squealing.
 

There is no need to point out that very few Matching Quality brake pad manufacturers make investments in research and development in this field.

A Brembo braking component is only placed on the market if it passes the most stringent tests, which are conducted in all conditions of use, including the most extreme. Starting with static bench tests, during which it undergoes higher load cycles than physically applicable to the vehicle in various environmental conditions.
 

Next, dynamic bench tests are conducted, to replicate the dynamics of the vehicle the component will be equipping. In this case too, loads above the operating loads are applied to ascertain strength, efficiency, comfort and functionality. Last but not least come the road tests. Seldom do economy component manufacturers have the resources, methodologies and machinery to do all this.

Brembo’s commitment to sustainability and to the environment embraces all the brand’s activities, from the initial research and development phases, in order to make increasingly sustainable products, solutions and processes. This approach is also evident in the various standard component manufacturing processes.
 

The paint used by Brembo entails drying using UV lamps. Since the UV paints are water-based, they differ from traditional paints made with chemical solvents. Energy consumption levels are therefore lower and no Volatile Organic Compounds are emitted.
