Defect description
ON CERTAIN MOTORCYCLES, THE SCREWS THAT ATTACH THE REAR BRAKE CALIPER TO THE REAR SWING ARM WERE NOT TIGHTENED CORRECTLY DURING ASSEMBLY. THE SCREWS COULD LOOSEN DURING VEHICLE OPERATION AND EVENTUALLY FALL-OUT, ALLOWING THE REAR CALIPER TO SEPARATE FROM ITS MOUNT.
Safety risk
IF THE CALIPER BECOMES TRAPPED BETWEEN THE REAR WHEEL AND THE SWING ARM, IT COULD DISCONNECT FROM THE BRAKE LINE, RESULTING IN A LOSS OF REAR BRAKING CAPABILITY AND INCREASING THE RISK OF A CRASH.
Manufacturer remedy
DEALERS WILL CHECK THE TORQUE OF THE REAR BRAKE CALIPER ATTACHMENT SCREWS AND RETIGHTEN THEM TO THE PROPER VALUE IF NECESSARY. OWNER NOTIFICATION BEGAN JULY 15, 2002. OWNERS WHO TAKE THEIR VEHICLES TO AN AUTHORIZED DEALER ON AN AGREED UPON SERVICE DATE AND DO NOT RECEIVE THE FREE REMEDY WITHIN A REASONABLE TIME SHOULD CONTACT BMW AT 1-800-831-1117.
