I recently changed my oil, and this morning i was doing a double check on the level before i took off. Now i am one of those super paranoid people that checks all the fluid at elast once a week, and when i looked over the rest of my fluids while i was in there i noticed that the brake master cylender level had droped like a half an inch, it has always been right at the max line...and now its more in the middle. I was hoping that it was the incline so i drove it around and stopped on a level surface, still low...Looked around, no signs of leaks. Drove it around a few miles, came back, parked still at the same level, and no leaks were forming under the car...

The oil, when i checked it the day before was right at the top line, wher it should have been since the engine takes 4.5 quarts and thats what i put in...Today it was below the low line, added about a half a quart(what i had left from 5 quarts) and now its in the middle of the two.

The resivor with the red cap on it, its long and skinny towards the front of the drivers side of the car, that is also about a half inch lower than normal

WTF is going on?
