Have problems with brake pedal going way down. Bled brakes and found air in left front only. (Lots of air.) Continued happening every couple days. Found what looked like a leak at master cylinder. Changed master cylinder. This did not help. Changed left front caliper and brake hose. There is no sign of leaking fluid, but I keep getting air in left front. Van does not lose any noticeable fluid in reservoir. Cannot get pedal to firm up solid. Will get better after bleeding, but always has a couple bubbles every time I crack bleeder. When I do bleed it I pump up the pedal and crack bleeder. It takes 4-5 times before I get hardly any fluid. A lot of air getting in somewhere.

HI there, often this is a faulty master, but as you have already changed it this is a bit strange, I would get 3 brake hose clamps and close off all hoses, see if the pedal is hard, re bleed with a power bleeder if yo can, keeping the clamps on the wheel lines that you are not bleeding, try this.
