could have a leak in your brake booster, with it in gear put your e brake on( make sure it works) then take your foot off the brake, if the problem goes away then it's your booster, you could also pop the hose off your booster with someone holding the brake for you just plug the end of the hose with your thumb, should smooth out after a few seconds if it's your booster
