A quick search of available postings seems to indicate that a conventional 'pump-the-pedal' or pressure bleed is insufficient during system flushes on vehicles with brake induced traction control such as a '99 ML 320. Some postings describe a bleeding problem with ABSs as well.

Can anyone explain and, perhaps, suggest a method which would allow a DIYer to perform a thorough flush on this vehicle without connection to diagnostic equipment (which, I assume, actuates applicable solenoids, etc)?

Thanks in advance.
