My 1982 240D's brakes are fantastic even when the car is fully loaded, not much pressure on the pedal is required to bring it to a halt from freeway speeds and only a gentle touch to prevent it from rolling on hilly stop signs .

Begin with a proper four wheel bleed and go from there .

Remember : simply having vacuum to the booster isn't sufficient ~ it needs to be able to HOLD the vacuum for at least 24 hours .

I too have heard many times that a W116 booster is a good upgrade .
