The issue
On certain C30 vehicles, the master cylinder to hydraulic brake booster attaching bolts may have been over tightened resulting in stripped threads and/or cracking of the booster casting. This could result in the master cylinder separating from the brake booster during a brake application and may cause a loss of vehicle control without prior warning.
