What NHTSA recorded

Fatigue cracks may develop in the brake vacuum booster housing. This may cause a vacuum leak and reduce the effectiveness of the brakes. After prolonged use, the cracks may develop to the extent that the booster may separate from the vehicle.

Remedy

Vehicles will be inspected for fatigue cracks in the brake vacuum booster. Those without cracks will have a support brace installed. Those with evidence of cracking will have a new brake vacuum booster and support brace installed. This service will be provided at no charge.
