P-DEF (Pyroclast® Dynamic Energy Filter) by EVOCorse is the innovative solution for optimizing the performance of the most powerful braking systems. Pyroclast® is a groundbreaking material developed through years of research in collaboration with leading institutions. Its use in braking systems is protected by an international patent. Thanks to its exceptional insulation properties and high compression strength, these plates deliver significant benefits for racing braking systems. P-DEF plates are placed between the brake pads and the caliper pistons, acting as a barrier to the heat generated during braking. This effectively helps reduce vapor-lock issues, which are caused by brake fluid overheating under intense braking conditions. Tested by top rally drivers, P-DEF is a reliable, ready-to-race component available in a variety of configurations for calipers, pads, and discs. The material’s lightweight design and thin profile (only 1 mm thick) are compatible with most high-performance systems, offering the following benefits:

• Reduced vibration damping

• Significant reduction in brake temperature issues

• Quicker attainment of optimal pad temperature

• Enhanced braking performance

The temperature of brakes with P-DEF plates is sensibly lower than brakes without P-DEF pads.

This graphic shows how braking time is 0.500 seconds faster when the car uses P-DEF plates on brake pads.
