How the Finishing of Different Surfaces of Brembo Racing Brake Discs Affects Performance

The distinctive groove design creates different performances: How does the various types of finishing on the surface of the brake disc of the BREMBO affect the performance?

        The brake disc is one of the main conversion options for the racing team. The team can apply it to the vehicle during any weekend event. The brake discs are different, and a series of different characteristics can greatly affect the braking performance. One of these features is the finishing of the brake disc surface, which is one of the potential factors that can affect the type of brake.

In fact, the difference in the brake phenotype is that:

1. Initial response (sensitivity)

2. Control and regulation

3. Release

4. Wear of brake pads

5 brake disc wear

There are many other variables that need to be considered when designing the brake disk surface type. Changing some of these variables can greatly affect the overall performance of the brake disc. When designing the groove of the brake disc, the following variables need to be taken into account (this is just a part of many variables):

Depth of groove

2. The angle of the groove

3. The length of the groove

4. The number of grooves

The brembo racing series offers four different surface types of brake discs depending on the application, the intended use, the preferences of the driver, other technical requirements of the application or the chassis of the vehicle.

Brembo punch brake disc

        Punched brake discs are suitable for a wide range of applications, operating temperatures and driving conditions (especially rainy days) but are rarely used on track.

        Advantages: Provides excellent initial response while continuously cooling the braking surface. This type of brake disc is lighter than many other brake discs.

        Disadvantages: Punched brakes are generally more prone to thermal cracking if they are used at extremely high temperatures (typical in competition). However, this also depends on the configuration of the track, rider and chassis.

Brembo type 1 brake disc

        The surface of Brembo's "8 straight grooves" focuses on maintaining a stable braking feel and improving the ability to withstand thermal breakage.

        Advantages: Brake stability at any temperature, reduced brake disc wear, continuous ventilating and cooling of the brake surface for optimum performance.

        Disadvantages: The "initial response" or "sensitivity" of Type 1 surface standard brake discs is lower compared to Brembo perforated brake discs, Type III brake discs, and V-brakes.
