hi arty b- that is the exact procedure i have used on dual master cylinder replacements since the first ones in 65 on a variety of models. only difference i do is when i mount the new master with the little bleeder hoses on and quickly make a loose connection of the lines to the ports, i dont rely on it dripping until is streams. that seems to risk air getting in. i have an associate steadily press pedal and hold it to floor while i tighten the port fittings. fluid will first spit out around the port threads expelling any air and then it will stream. may have to loosen the port threads a 2d time and repeat, but it always works. and havent so far had to use f bombs during the job. heres a good one from the shyster file- hustler mechanic said it wont work due to abs system getting aerated. did it this way recently on a 92 volvo 240 and 01 merc. both worked fine. in fact drove merc from se fla to mountains of upper pa. traversing stinking creek md. 2k miles with no problems. hustler btw wanted $400 to do merc master due to alleged advanced tech mysteries of the abs . what think you? as we said in nam and pork chop hill- give em hades. regards oldduke
