Brembo 4KC.8039A PISTA 4 TY5 2-Piece Rear Brake Discs 345x28mm

The Brembo 4KC.8039A PISTA 4 TY5 represents professional-grade braking performance engineered for high-performance and racing applications. These 2-piece rear brake discs combine Brembo's legendary racing heritage with advanced thermal management technology.

Key Specifications:

• Disc diameter: 345mm (13.6 inches)
• Disc thickness: 28mm
• Center bell offset: 54mm
• 2-piece floating disc design with aluminum hat
• Type 5 mounting configuration
• Rear axle application

Performance Features:

• 2-piece construction reduces unsprung weight while improving heat dissipation
• Aluminum center bell allows independent thermal expansion from the cast iron rotor ring
• Floating disc design reduces heat transfer to wheel bearings and hubs
• Ventilated rotor design provides superior cooling under extreme braking conditions
• High-carbon cast iron rotor ring delivers consistent friction characteristics
• Designed for track use and high-performance street applications

Brembo PISTA (Italian for "track") components are engineered for enthusiasts who demand race-proven technology. The 2-piece design not only reduces weight but also allows the rotor to expand and contract independently from the mounting bell, reducing thermal stress and extending component life during repeated hard braking cycles.
