i've read alot in the searches for brake bleeding from this site and others,however,i don't know what kind of system i have and what type of bleeding i can use at home.some places say to pump the brakes and hold,then open the bleed screw.others say to turn on the engine,let the pressure build and then bleed.i have a '95 s500 with abs&asr but i don't know which system to follow.can somebody help out,please?thanks
