I've had my front suspension apart for several days now installing new parts. The front brake calipers have been pulled off the car to be stripped and repainted. After reinstalling them today while attempting to bleed them I've hit a huge problem, the brake pedal has no pressure in it. I've got the bleeder screws open right now and the master cylinder cap open attempting to gravity bleed the system. I'm hoping there is just air in the brake booster, but I would greatly appreciate input or solutions.
