Drilled: Suitable for a wide range of applications, operating temperatures and driving environments (especially wet weather).
+ Benefit: offers the highest initial response of all the available disc face types while continuously refreshing the braking surface and being also typically a bit lighter.
- Drawback: Drilled discs are generally more prone to heat checking and thermal cracking if used consistently at extremely high temperatures. This however, really depends on the track, driver, and chassis setup.
Type-1: Brembo “8 straight – slot” face type with an emphasis on stable brake feel and improved resilience against thermal cracking.
+ Benefit: stable braking feel at all temperatures, low disc wear, and continuously refreshing the braking surface for optimum performance.
- Drawback: The Type-1 standard disc face has the lowest “initial response” or “bite” compared to Brembo Drilled, Type-3 or Type-5 discs.
Type-3: Aggressive Face Type; motorsport developed face type with an emphasis on high initial response while maintaining a smooth pedal release.
+ Benefit: highest overall braking confidence, control, and allows the driver to spend less time on the brake pedal. When chasing the fastest lap time, less time on the brake pedal typically leads to a quicker lap time.
- Drawback: Any disc with an aggressive face type like the Type-3 will have a higher chance to mechanically abrade the pad and disc surface leading to quicker or uneven pad wear. However, this really depends on variables such as car setup or track layout
