Ned,
I had it happen west of Memphis last September on my 116 300SD on my
way to Virginia International Raceway...... Brake pedal was like
pressing on a brick.......
The dealership had a reman and was on my way the next morning $800
lighter in my wallet... Not what I would choose, but it got done....
Take care,
Chuck

Can vacuum pumps fail suddenly and completely?
During my commute from work this evening, my '95 E300D
suddenly started shifting harshly. Then at the next red light, the
brakes
required a lot of peddle pressure.
I pulled over to check things out and the engine wouldn't shut
off. That's
when I realized I had lost vacuum.
Can't find any obvious big leaks or anything. With the engine
running, I
disconnected the big vacuum line to the master cylinder, and it
had NO
vacuum at all.
I've replaced other vacuum pumps on my MB fleet when they were
getting weak
or noisey. But I've never had a total failure.
Has anybody else experienced this?
That's the most common actual vacuum failure - sudden. It's USUALLY a
leak, but the pumps can fail without ANY warning.
