DBA DBA42311 Series HD Plain Brake Rotor - 4000

The DBA DBA42311 is a 4000 Series Heavy Duty (HD) plain brake disc engineered by Disc Brakes Australia — a trusted name in performance and OE-replacement braking systems. Built to meet or exceed OEM specifications, this rotor delivers reliable stopping power and durability for demanding driving conditions.

DBA's 4000 Series HD rotors are manufactured using a proprietary Geomet® corrosion-resistant coating on the hat and outer edge, combined with precision-machined rotor faces for optimal pad contact. The heavy-duty casting process reduces heat-related warping and extends service life compared to standard economy rotors.

Key Features:

• DBA 4000 Series Heavy Duty (HD) plain-faced disc rotor
• Geomet® corrosion-resistant coating on non-braking surfaces
• Precision-machined rotor faces for even pad contact and reduced vibration
• Heavy-duty iron alloy casting for improved thermal stability and longevity
• Direct OEM replacement — no modifications required for installation
• DBA Kp (Knurled Pillar) vane technology for enhanced heat dissipation
• Meets or exceeds ADR and international braking standards

The DBA42311 is designed as a direct-fit replacement rotor, making installation straightforward with no drilling, cutting, or special tools required beyond standard brake service equipment. It is an ideal upgrade for drivers seeking improved durability and consistent braking performance over factory rotors.
