( Service-InformationM otorcycle BMW NA Service Department Group: 34 Brakes December, 1987 34 012 87 (2262) For USA Only Damaged/Bent Brake Disc Rotors Complaint: Cause: Note: Pulsation of front brake lever during slow speed/coming to a stop. Generally occurring between 5,000 and 9,000 mil es. Disc Rotors being damaged during tire changes or wheel removal, transportation or storage. Tire Changes – Improper/careless handling of wheel removal, bead breaking and tire mounting. Transportation – Improper/careless handling of wheel removal by customer. When wheel is transported in a vehicle for tire change, brake disc is subjected to side loading as disc is wider than tire edge. Wheel should be supported so that disc does not contact trunk or other objects. Storage – When wheels are stored at your dealership awaiting customer pick-up, ensure that the discs are protected from side loads/impact. Disc Rotors are designed to withstand tremendous rotational load, but are not designed to withstand side loads as described above. Repairs from damage/abuse as described above are not defects in materials or workmanship and therefore are not warrantable. Very truly yours, BMWOF NORTAHM ERICAIN, C.
