This Protex Front Brake Disc Rotor replaces the original equipment unit on Nissan X-Trail models built from 2017 to 2019. 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. 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. Runout is held under 0.05mm at the mounting face, which prevents the pedal pulsation that follows a poorly machined rotor. Outside diameter is 340mm with a new thickness of 26mm and a minimum machining thickness of 26mm. New stock, 12 Months warranty, and dispatched from our Australian warehouse.
