DBA DBA42536 Series HD Slotted Brake Rotor - 4000 Front

The DBA DBA42536 is a 4000 Series Heavy Duty (HD) brake rotor from Disc Brakes Australia, engineered for drivers who demand superior stopping performance and durability beyond OEM standards. DBA's 4000 Series HD rotors feature the brand's signature Geomet® protective coating, providing excellent corrosion resistance and a clean appearance straight out of the box — no bedding-in rust period required.

These rotors are precision-machined to strict tolerances and incorporate DBA's Kangaroo Paw (KP) vane technology, an advanced internal vane design that dramatically improves airflow through the rotor for faster heat dissipation. Reduced operating temperatures translate directly to longer pad and rotor life and more consistent, fade-resistant braking performance — especially under heavy or repeated braking loads.

Key Features:

• 4000 Series HD designation — heavy-duty construction built to exceed OEM performance benchmarks
• Kangaroo Paw (KP) vane technology — optimized internal vane geometry for superior thermal management and cooling efficiency
• Geomet® corrosion-resistant coating — protects the rotor face and hat from rust and oxidation
• Precision machined to strict runout and thickness variation tolerances for smooth, vibration-free braking
• Slotted rotor design — continuous slots sweep debris and gases from the pad/rotor interface, maintaining consistent bite and pad conditioning
• Direct OEM replacement — bolt-on fitment with no modification required
• Manufactured to ISO 9001 quality standards by Disc Brakes Australia

DBA is an Australian-owned manufacturer with decades of expertise supplying rotors to both OEM and performance aftermarket customers worldwide. The 4000 Series HD line is a popular upgrade for SUV and 4WD owners looking for improved braking durability and heat management, particularly those who tow, load heavily, or drive in demanding conditions.
