This Mazda Genuine Front Brake Disc Rotor replaces the original equipment unit on Mazda CX-5 models built from 2019 to 2021. Supplied with a light protective oil film; clean with brake cleaner before fitting. Outside diameter is 338mm with a new thickness of 22mm and a minimum machining thickness of 24mm. Runout is held under 0.05mm at the mounting face, which prevents the pedal pulsation that follows a poorly machined rotor. This part is a common wear item on high-kilometre Australian vehicles and is worth replacing in pairs. We recommend fitting by a qualified technician and following the manufacturer's torque specifications. Every unit is supplied new with a 2 Years / 40,000 km warranty against manufacturing defect.
