DBA DBA52844.1S Series Slotted Brake Disc Replacement Ring - 5000 T3 Front

The DBA DBA52844.1S is a 5000 Series T3 slotted replacement brake disc ring designed for two-piece composite brake rotor systems. This front rotor ring is sold individually, allowing owners to replace only the worn cast iron friction ring while retaining their existing aluminum hat — a cost-effective solution for high-performance and track-driven vehicles.

Key Features:

• T3 Bi-Slotted Design: Delivers a smoother, more responsive, and quieter braking experience compared to standard slotted patterns
• Heat-Treated Cast Iron Construction: Robust material delivers unparalleled strength and durability under intense braking conditions
• Kangaroo Paw Vane Ventilation: Provides up to 30% more surface area and 20% improved cooling efficiency over conventional straight vane designs
• High Carbon Alloy Ring: CBN machine-turned finish ensures precision fitment and optimal pad contact
• Two-Piece Compatibility: Designed to pair with DBA 5000 Series aluminum hats (T6061-T6), secured with National Aerospace Standards (NAS) bolts and crimp nuts
• Reduced Unsprung Weight: Aluminum hat compatibility allows for uniform radial disc expansion and reduced heat transfer from disc to hub
• ECE R90 Approved: Meets European safety certification standards for brake components
• Thermographic Heat Paint Markings: Color-shifting indicators provide a visual reference for heat thresholds reached during use

When replacing only the ring, DBA recommends thoroughly inspecting the aluminum hat for damage or wear before reinstallation. Use DBA spec bolts and nuts, and torque the NAS nut and bolt assembly to 13 Nm (9.6 ft-lb). Sold as a single replacement ring.
