Engineered for Australian operating conditions, this Protex Brake Master Cylinder suits BMW X3 AWD models built from 2018 to 2021. The Aluminium construction is corrosion protected for long service life on Australian roads. Built to original equipment specification with all seals, hardware and fittings required for the job. Every unit is pressure tested and inspected before packing. Bleed the brake system thoroughly after fitting and check for leaks before road testing. Brake components should always be replaced in axle pairs to keep braking balanced. Check the fitment list against your build date and VIN before ordering, as running changes were made mid-generation. New stock, 24 Months warranty, and dispatched from our Australian warehouse.
