Perforated or scored brake disc: which one to choose and why?
In the exciting world of motor racing, the constant search for technological advances and performance improvements is a constant. One of the key areas that has undergone significant evolution in this field is sports braking. Ceramic braking systems, regenerative braking, electronic control systems and other innovative technologies have revolutionised the way racing vehicles stop and improve their performance in extreme situations.
In this SDT Brakes blog, we will explore in detail the advances and innovative technologies that have transformed the world of sports braking in racing. We will focus specifically on ceramic brake systems, regenerative braking, electronic control systems and other emerging technologies.
We will highlight how these innovations have improved both the performance and efficiency of sports brakes, allowing drivers to face the challenges of the track with greater confidence and achieve exceptional results. Join us on this journey through the evolution of sports brakes and discover how these innovative technologies have changed the game in the exciting world of motor racing.
Perforated or scored brake disc? Advantages and disadvantages
efore diving into the details of each disc type, it is important to understand the general advantages and disadvantages of drilled and scored brake discs.
Advantages of drilled brake discs
Increased heat dissipation: The holes in drilled brake discs allow for better dissipation of heat generated during braking. This helps prevent overheating.
Improved gas and water expulsion: The holes in the drilled brake discs help to expel gases and water that accumulate between the brake pads and discs. This improves contact between them and ensures more efficient and consistent braking.
Disadvantages of drilled brake discs
Lower resistance to cracking: Perforated brake discs are more likely to crack due to the weakening of the disc due to the holes. This makes them less durable and reliable compared to solid or scored discs.
Increased brake pad wear: Holes in drilled brake discs can wear brake pads more quickly compared to solid or scored discs. This may require more frequent brake pad replacement.
Corrosion sensitivity: Exposed holes in drilled brake discs may be susceptible to corrosion and rust. This can affect their aesthetic appearance and, in extreme cases, compromise their performance.
Advantages of scored brake discs
Improved gas and water expulsion: The grooves in scored brake discs help to expel gases and water that accumulate between the brake pads and discs. This improves contact between them and ensures more efficient and consistent braking.
The grooves clean the brake track of brake pad friction material deposited in the grooves.
Disadvantages of grooved brake discs
Reduced heat dissipation capacity: Unlike perforated brake discs, scored discs do not dissipate heat as efficiently. In heavy and prolonged braking situations, this can lead to an increase in temperature and, potentially, a decrease in braking performance.
Possibility of noise: In some situations, scratched brake discs may generate a characteristic sound during braking. This can be considered a disadvantage for those seeking a quieter driving experience.
Differences between drilled and scored brake discs
Now that we have reviewed the general advantages and disadvantages of drilled and scored brake discs, it is important to understand the key differences between them.
Perforated brake discs are characterised by holes that run across the entire surface of the disc, creating a pattern of perforations in the form of circles or rectangles. These holes allow gases, water and debris to be expelled from the brake pads, improving heat dissipation and maintaining more consistent braking.
On the other hand, scored brake discs have grooves or grooves on the disc surface. These grooves have the function of evacuating water and gases, improving pad-to-disc contact and reducing the effect of aquaplaning in wet conditions.

Which brake pads are suitable for drilled and scored brake discs?
Choosing the right brake pads to complement drilled or scored discs is essential to ensure optimum performance. In general, it is recommended to use high performance brake pads that are specifically designed for use with drilled or scored discs.
Ultimately, it is important to follow the vehicle manufacturer's recommendations and consult with brake experts to select the right brake pads to suit your needs and the type of discs you choose.
Conclusion
The choice between drilled and scored brake discs depends on your personal preference, driving style and the conditions in which you normally drive. Both types of discs offer distinct advantages and disadvantages in terms of performance, heat dissipation and durability.
Perforated brake discs provide better heat dissipation and may be more aesthetically pleasing. On the other hand, scored brake discs offer better performance in extreme conditions and their function of cleaning the brake track improves the contact of the brake pad friction material with the brake disc track surface.
It is essential to match the right discs with the right brake pads for optimum performance and to ensure your safety on the road. Consult with trusted professionals and consider your specific needs before making a final decision on the brake discs you choose for your vehicle.
