Brembo 355x32mm 20mm Airgap T5 LH PISTA Replacement Disc

This is a Brembo 355x32mm 20mm Airgap T5 LH PISTA replacement disc, part number 09A02713. It's designed as a direct replacement for specific high-performance braking systems, particularly those utilizing Brembo's PISTA line of components. The 'Airgap' design refers to a specific internal vane structure that helps manage heat more effectively than traditional solid rotors. This is crucial for applications where extreme braking forces are common, such as track days or competitive racing, as it helps prevent brake fade and maintain consistent stopping power.

The 355mm diameter and 32mm thickness are substantial dimensions, indicating this rotor is built for vehicles that require significant braking capacity. The 'T5' designation typically points to a specific material composition or heat treatment process that Brembo uses for their racing-oriented discs, aiming for improved thermal stability and durability under heavy use. The 'LH' signifies it's the left-hand side rotor for a specific caliper and mounting arrangement. These rotors are often paired with Brembo's multi-piston calipers and specialized brake pads to create a complete, high-performance braking package. Proper installation and bedding-in procedures are essential to unlock the full potential and longevity of these specialized components.

When replacing a rotor like this, it's important to ensure you are using the correct side (LH in this case) and that the mating surfaces of the caliper and hub are clean. Because this is a specialized performance part, it's designed to work within a specific system. If you're rebuilding a high-performance braking setup or replacing a worn rotor on a track-focused vehicle, this Brembo PISTA disc offers a well-built option designed for demanding conditions.
