When i'm driving, sometimes there will be brake pressure and somtimes there won't. If i apply pressure for a few seconds, the pedal loses presure and goes to the floor. I have to pump the brakes to get the car to stop. I tried bleeding the brakes and got through the back to wheels fine, but when i tried to bleed the front right brake, air bubbles kept coming out. After refilling the resivoir for the 3rd time (it never got completly empty), i got the idea that it might be somethign more complicated. I was able to bleed the front left with no problems but the same thing kept happening when i tried to drive it. I checked all the lines and can't find any leaks, but i have an oil leak so i might be missing something thinking its just oil and not brake fluid. There is some black fluid underneath where the brake booster connects to the master cylinder but i don't konw if its coming out of there or is oil . I can also hear some air come out of the brake booster inside the car but i dont' know if that is normal. My brake fuild is also pretty dark, i know i should flush it out and replace it but could that be the problem? I don't know too much about brakes and i don't want to take apart the whole system before i know what to look for. Any ideas?
