thanks, i like the homemade bleeder, should have checked this website before spending $22 on the one from IPD. THat one has to use a spare tire for the air source. Have you tried to bleed your brakes using it? or atleast a power bleeder? I think the cap on the MB is the same as the one on the volvo but will check and if not, get a new cap and cut up the old one on the MB.
