No brakes in the morning. It will definitely wake you up more than coffee.

Here are some pictures. Could the check valve be in the intake? Nahh couldn't be right..? This braking problem always appears after the car has sat there for a while. This time it was just 2 hours and happens as soon as you start the engine and roll and then try to brake. Never has it done that it while driving or normal operations thank God! From what I see the hose connects from the brake booster to the intake. Nothing else in either end of the hoses.
