Brembo 09.A820.1S Sport Brake Disc Rotor TY3 Slotted 314mm Ventilated

The Brembo 09.A820.1S is a Sport brake disc rotor belonging to the Brembo Cool Line — engineered for drivers who demand more than standard OE performance. Featuring the iconic TY3 (Type 3) groove pattern derived from professional motorsports, along with the embossed Brembo logo on the braking surface, this disc delivers a noticeable upgrade in feel, grip, and fade resistance over conventional rotors.

TY3 Slot Technology:

• Slots continuously clean and renew the pad friction surface for consistent braking performance under repeated use
• Prevents water film build-up between pad and disc on wet surfaces for reliable wet-weather stopping power
• Higher friction coefficient delivers improved initial bite and more responsive braking modulation
• Slot design is race-proven in GT and endurance championships including the 24 Hours of Le Mans

Construction & Quality:

• High-carbon cast iron construction minimizes noise, vibration, and harshness (NVH)
• UV coating provides superior corrosion resistance that exceeds OE standards
• PVT (Pillar Vane Technology) internal ventilation for enhanced heat dissipation and fade resistance
• ECE R-90 certified — meets European safety homologation standards for OE-equivalent or better performance
• Plug-and-play installation with no modifications required — fully interchangeable with OE discs
• Includes mounting/fixing screws for straightforward installation
