Bled brakes (pass rear, driver rear, pass front, driver front). Bled all of the old dark fluid out of the rear brakes until clean fluid flowing through with no air in the lines. Did the same on the front brakes, but there is a lot of air bubbles seen flowing through the tube. I've gone through two pints of fluid on the fronts, and still get air bubbles. There are no visible leaks in the system, and there is no loss of fluid when applying brakes for an extended amount of time. Brakes got soft after car was sitting for the winter. There is a small amount of pressure while car is off, but I can get the pedal to reach the floor with some effort. Any other suggestions would be greatly appreciated.
