2014 Nissan Versa engine problems

Went out to start car push in clutch and car rolled out into street had brake on but did not hold and after starting motor the brakes worked ok with engine running.. Everytime I start the car if you are on a slope the car will roll and hit something. I checked threw out the day and found that when car is not running you have no brakes. You do not have any power brakes when engine stops they become hard immediately lose power assist not like other cars where you have 2 or 3 applications before brake loss.
