I need some advice.
I've got a vacuum problem in my '85 300D. I was driving to the mountains (a couple hours away) on Friday and when I stepped on the brakes to pull into a fuel station it felt like I had no power brakes. My motor will not shut off with the key. The auto transmission is shifting harshly. And eventually, I ran out of vacuum to operate the power locks. My father and I separated the line not far from the vacuum pump and felt no suction on the line. A friend said I could buy a rebuild kit for the vacuum pump. Does this sound like what I need to do? Any other suggestions? Any help would be greatly appreciated.
