Setup, Compatibility & Care
Installation must be performed by a qualified mechanic to ensure safety and longevity. When installing the 09.A819.11, ensure the wheel hub surface is cleaned of all rust and debris to allow the 67mm centering hole to seat perfectly flush. A critical step in the setup process is strictly adhering to the 130 Nm tightening torque specification to prevent rotor warping and hub stress. Before the first drive, use a brake cleaner to remove any storage oils from the surface of the disc. For long-term care, avoid aggressive high-pressure washing directly on the hub area when the brakes are hot, as this can cause thermal shock to the metal components.
