If you're going to bleed the brakes, have your assistant pump a few times and hold while you open the bleeder to let the fluid out. Then close the bleeder while the assistant holds the pedal to the floor. Then do it again, until the fluid is free of air.
You don't say whether the ABS light is on or off at this time but if it's on, there's no ABS function so that's a safety issue. Get it corrected ASAP.
If your mechanic let the car go with bad brakes, I think you need to find someone who takes it more seriously, like a Ford specialist.
