DBA DBA4600 Series HD Plain Brake Rotor - 4000

The DBA DBA4600 is a 4000 Series Heavy-Duty (HD) plain brake rotor from Disc Brakes Australia, engineered as a direct OE-replacement upgrade for drivers who demand performance beyond factory braking standards. The 4000 Series HD variant features a smooth OE-style rotor finish, making it popular for drivers who want the benefits of a 4000 Series rotor while maintaining a factory-style appearance.

Key Features:

• Cast from high-carbon alloyed iron and processed through Thermal Stability Profiling (TSP), DBA's metallurgy is engineered to handle the increased stress and heat generated under intense braking applications, repeatedly.
• Features DBA's Kangaroo Paw ventilation design, implementing a series of 144 diamond and teardrop patterned pillars that achieve up to a 30% increase in surface area and a 20% improvement in cooling efficiency compared to a traditional straight vane design.
• Heat treatment cycles realign the microstructure of the iron, resulting in increased rotor stability and durability.
• CBN (Cubic Boron Nitride) machine-turned finish minimizes disc thickness variation and the potential for pad knock and resulting premature wear.
• Heat-sensitive paint markings change color at specific temperature thresholds to assist with monitoring braking temperatures and rotor fatigue.
• Packed with performance-enhanced features typically found on the race track, the HD rotor is a natural fit for extreme environments, and is ideal for load-carrying and heavy vehicles such as SUVs and 4WDs, particularly when towing trailers or campervans.

Disc Brakes Australia is an Australian-owned manufacturer with more than three decades of manufacturing expertise, supplying premium performance disc brake rotors from its manufacturing plant in Sydney, Australia. The DBA4600 is sold individually — order two for a complete axle set.
