I know i need new pads and rotors. I have to refill my break fluid about once a week, also when i push on the breaks they make a bubbling and a squeeking noise. the worst part is that when i press on the breaks really hard, my car goes up in smoke, kinda a greyish white color that comes from the back of the car to the front. Can anyone help me with this. my master cylender is leaking but i am not sure what would be causing the smoke......
