I have a 2001 C240 base. I can't find the air and also a no fluid flow in one of the brake lines and just drips. This is all after changing caliper and the reservoir running dry and staying like that a few days. My questions is, does the ABS on this car have a bleeder valve? If not, what can be done without a scan tool? I bled all other three wheels twice.
Thanx

 

I don't think there's a bleeder valve, unless you're talking about the valves on the calipers.

Can you be more specific? The fluid has to be going somewhere. Is the car leaking?

 

Nope, no leaks at all. I bled from all three calipers and still no breaks and the caliper I just replaced brand new, the brake line oy drips and doesn't flow, but came out when I put the vac bleeder directly on it.

 

Are you actually getting air bubbles coming out of the wheel in question? If not, the wheel might be properly bled. Is the wheel acting funny?

I'm guessing the wheel in question is in the rear, where the total pipe/hose distance is longer. Remember that flow losses increase with pipe length.
