Boy did I screw up.

I was going to flush out the old brake fluid on my 83 300D. I was using a Motive pressure bleeder to pressurize the system when the worst happened. As I was doing the first wheel (right rear) I accidently let the master cylinder reservoir go dry. Suddenly as I was letting fluid out of the wheel cylinder, I got a whoosh of air. Now the system has a lot ofair in it. I filled the reservoir again, and pumped up the pressure bleeder several times, but all I get is air, no fluid.

Do I need to bleed the master cylinder now? If so, how.

The brake pedal never gets firm, no matter if the car is running or not.

HELP!

Glenn
