Based on our shop experience specializing in heavy-duty brakes since 1985:

• Surface Preparation: Thoroughly clean all machining oils from the rotor friction surface using a non-residue brake cleaner before installing pads.
• Bearing Race Installation: If not pre-installed, ensure wheel bearing races are pressed fully into the rotor hub seat to prevent bearing wobble or premature race failure.
• Hub Seal: Always use a fresh grease seal to prevent debris ingress into the internal bearing pack.
