This RDA Front Brake Disc Rotor replaces the original equipment unit on Nissan X-Trail models built from 2018 to 2020. Supplied with a light protective oil film; clean with brake cleaner before fitting. The Steel casting is high-carbon enriched for better damping and quieter braking. Runout is held under 0.05mm at the mounting face, which prevents the pedal pulsation that follows a poorly machined rotor. The casting is fully machined, dynamically balanced and given a protective coating on the hat and edges to slow surface rust. Outside diameter is 296mm with a new thickness of 30mm and a minimum machining thickness of 24mm. Sold new with 2 Years / 40,000 km warranty cover and full technical support.
