My 1982 300D Turbo suddenly lost power assist to the brakes while I was parking. When I turned the key off, the engine kept running. Also, door locks stopped working entirely (they never worked very well).
Well, I checked for obvious leaks in the vacuum lines, and found none. Then, I dismantled the main tube from the vacuum pump and started the engine. When I placed my thumb over the open line, I felt no vacuum from the pump.
Is the vacuum pump the only possible culprit at this point? Or, could there be a bad coupling or gear that drives the pump? If I must replace the pump, or a coupling to it, how difficult is this? Any pointers on doing this job?
Thanks,
