If you have a hard brake pedal and an engine idle problem, it would almost have to be a vacuum problem, because a loss of vacuum would cause both of these issues.
This is the best I can give you without seeing the vehicle.
Is there an engine light on? If so, have it scanned to see what trouble codes you get.
Then address them as necessary. If you get the trouble codes and have any questions, leave a comment and I'll try to help you.
