Recently I purchased a 300 CE "92.
Have a problem with the brakes, They seem to have a mind of their own.
After driving approx 45 miles they LOCK UP.
It seems to be some kind of vacuum problem as the brake pedal gets
gradualy stiff,it goes in to a violent shake (abs?) and if I let it go
it will lock up the front wheels right front first (if it makes any difference)
I have adopted a new driving style (STAB the brake pedal hard)once in a while and they seem to unlock or not go further in to lock up.
That is until the pedal starts to stiffen up again.
It is not the most pleasurable way to drive and very disconcerting to my fellow drivers on the road. I have a '88 260E , had a 89 300E and never
experienced this kind of problem.
Any help ideas will be greatly appreciated.Thank You very much...
