⚠️ Installation Tips
Crucial: Please carefully measure the diameter of your old brake disc and confirm it matches the 120mm or 140mm option before purchasing. Also, verify that your wheel hub uses a 3-bolt pattern.
Thoroughly clean the wheel hub mounting surface and the new disc with a brake cleaner before installation to remove any protective oils, ensuring proper friction and safe braking.
When tightening the 3 mounting screws, use a cross-tightening sequence (tightening them evenly one after another) to ensure the disc sits flat and true, preventing brake vibration or pulsing.
