CHRYSLER issued a recall on the DART, and DART models

On certain vehicles, engine oil may migrate from the vacuum pump into the brake booster. Prolonged brake booster diaphragm exposure to engine oil could cause the diaphragm to fail, leading to a loss of brake booster assist. This may result in increased brake pedal effort, which could increase stopping distances, potentially resulting in a crash causing injury and/or damage property. Correction: Dealers will inspect the brake booster grommet for the presence of oil. If no oil is found, the vacuum tube assembly will be replaced. If oil is found, the vacuum pump, vacuum tube assembly, brake booster and master cylinder will be replaced.
