Engineered for Australian operating conditions, this DBA Rear Brake Disc Rotor suits Nissan X-Trail models built from 2021 to 2022. Outside diameter is 276mm with a new thickness of 30mm and a minimum machining thickness of 30mm. The Cast Iron casting is high-carbon enriched for better damping and quieter braking. Vane geometry is matched to the original design so cooling airflow and thermal expansion behave as the factory intended. The casting is fully machined, dynamically balanced and given a protective coating on the hat and edges to slow surface rust. Supplied with a light protective oil film; clean with brake cleaner before fitting. Runout is held under 0.05mm at the mounting face, which prevents the pedal pulsation that follows a poorly machined rotor. New stock, 36 Months warranty, and dispatched from our Australian warehouse.
