NHTSA recall 83E010000 · Equipment
Service brakes, hydraulic › Power assist › Vacuum
The defect
Shell assemblies of the booster may separate and fail to transmit necessary forces to master cylinders. This problem IS due to insufficient crimping of shell members to resist shock and vibration in service. A separate defect exists in power boosters assembled with master cylinders. These assemblies may not have the correct master cylinder attached. The master cylinder may not transmit forces from the brake pedal to the rear brake system. The two defects are mutually exclusive; there are no power brake boosters with inadequate crimps that also have the incorrect master cylinder attached.
The remedy
Manufacturer IS replacing all booster units stocked by distributors with new units and IS attempting to locate retail purchasers for replacement of their units. Owners will be reimbursed for the cost of replacing units installed on vehicles.
