The defect
The rear brake wheel cylinder retainer on the involved vehicles may not have been properly installed. Should the wheel cylinder retainer become completely disengaged, the wheel cylinder could move outboard causing a loss of brake fluid and a loss of rear braking action.
The remedy
The dealer will reposition the rear wheel brake cylinder retainers, free of charge, on all affected vehicles.
