Brembo 09779244 2-Piece Floating Brake Rotor

The Brembo 09779244 is a high-performance 2-piece floating brake rotor designed for superior braking performance and weight reduction. This premium rotor assembly features Brembo's proven floating disc design, combining a lightweight aluminum bell/hat with a high-carbon cast iron braking surface connected by floating mounting hardware.

Key Features:

• Two-piece floating design allows thermal expansion while minimizing warping and deformation
• Lightweight aluminum bell reduces unsprung weight for improved handling and vehicle dynamics
• High-carbon cast iron rotor ring provides excellent thermal performance and durability
• Floating bobbin mounting system reduces stress from thermal expansion
• Direct OE replacement design works with stock brake calipers
• Corrosion-resistant coating for enhanced protection and appearance

Brembo's 2-piece rotor technology delivers up to 30% weight reduction compared to equivalent one-piece rotors, while also reducing permanent thermal deformation by up to 70%. The floating design allows the rotor ring to expand elastically during heat cycles, preventing cracks and warping while maintaining consistent braking performance across a wide temperature range. The aluminum hat dissipates heat more efficiently than traditional cast iron, keeping the entire braking system cooler during aggressive driving or heavy use.
