If your brakes go spongy after using them hard a few times then there is a simple cause..it's either air or water or both. Nothing else.
Sometimes it helps to leave the bike on its sidestand overnight with the reservoir cap off and the lever clamped to the bar. It's a common trick. Also I often tap the brake lines when bleeding them - helps the air rise back up the line to the reservoir.
