Your ROs should specify parts and prices. Are they Mercedes part numbers? Ask them the source of the parts - new MBZ parts via the MBZ parts distribution system or what?

Always ask for the old parts back.

Look for signs of leakage from the master (under the dash) and slave (bottom of the bell housing. Brake fluid is water soluble and has a bitter taste. Any leakage of fluid means air could be getting in, but the problem could also be caused by an "internal leak", which will not leave external fluid evidence.

The parts had MB part numbers, so they were OEM. Whether they were rebuilt is another issue.

I got the original slave back when i had it replcaed the first time 'round, but neglected to ask for the old master.

No leaks are apparent anywhere. car is completely dry inside & out. it's been my contention that there is an internal leak based on the behavior and feel of the pedal. I suspect that the MB service department is hesitant to actually pull the units because it would have to be billed as warranty work.

I've also spoken to a couple of independants who are quite knowledgeable about MBs and they are as baffled as I.

as an aside, no one has been able to give me a reasonable explanation as to why the water & oil temp of my car is as high as it is.

I've replaced the t-stat, water pump, & most of the hoses last year. The radiator and oil cooler still appear to function properly. i'm starting to think thatt he oil t-stat is faulty.

i also had the cat removed from my car. the thinking was that if the cat is starting to get plugged up, it could be creating enough extra backpressure to increse the engine temp. so far, the temps have dropped only slightly (<5 deg. c)

Perhaps the temperature gauge is faulty.
