Help somebody!!!! My brakes are working but I have noticed something different in the last few days or so. When I press my brake and hold it down (as if I were waiting at a stop light) it seems to sag in a little bit. It almost feels like I am bleeding my brakes very very slowly. The first time I noticed this was a few days ago... is when I held my brake down, a little while after I was pressing the gas at the same time... Help! What is the problem??????
