Defect / Noncompliance Description

*Describe the defect or noncompliance:
The brake master cylinder may have been improperly fastened to the brake booster assembly during production, resulting in loose or missing tie rod nuts. During application of the brake pedal, a bending load may occur upon the brake booster assembly tie rod studs. As a result, the tie rod studs may break, leading to the brake master cylinder separating from the brake booster assembly and a failure to comply with Federal Motor Vehicle Safety Standards (FMVSS) 135 – Light vehicle brake systems.

*Describe the safety risk:
If the brake master cylinder separates from the brake booster assembly, the driver may experience diminished, or loss of, brake function, increasing the risk of a crash or injury.

Describe the cause:
The brake master cylinder was improperly fastened to the brake booster assembly during production.
