DBA DBA42281 Series HD Slotted Brake Rotor - 4000

The DBA DBA42281 is a 4000 Series Heavy Duty (HD) brake rotor from Disc Brakes Australia, engineered for drivers who demand superior stopping performance and long-term durability beyond what standard OEM rotors provide. Featuring DBA's signature Geomet® protective coating, this rotor resists rust and corrosion from the first installation, keeping the rotor looking and performing like new.

DBA's 4000 Series HD rotors feature the brand's proprietary Uni-Directional Slotting (UDS) pattern, which continuously sweeps debris, dust, and gases away from the pad surface for consistent, fade-resistant braking. The advanced slot geometry also helps seat brake pads more quickly and maintains a clean, consistent pad contact face throughout the rotor's service life.

Key Features:

• DBA 4000 Series Heavy Duty (HD) vented brake rotor
• Uni-Directional Slotting (UDS) for continuous pad sweep and improved bite
• Geomet® corrosion-resistant coating — no initial rust bloom
• Thermally stable metallurgy for reduced heat-induced warping and cracking
• Zinc dichromate hat and vane coating for full corrosion protection
• Manufactured to strict ISO/TS 16949 quality standards
• Direct OEM replacement — no modifications required for installation

The DBA42281 is a direct-fit replacement rotor designed for precise OEM fitment, making installation straightforward. Whether used with OEM brake pads or upgraded performance pads, the 4000 Series HD rotor delivers enhanced thermal capacity, improved fade resistance, and extended service intervals compared to stock rotors.
