Is there any special procedure or tool required to bleed the brakes on an ABS/ASR equipped 94 w124 E320. I'm planning on flushing as much of the old fluid out as possible (as I have NO idea when the P.O. did it last) and just want to make sure I do it correctly as I have searched/read that there is a different procedure for ABS equipped cars, but haven't found what that procedure is. TIA for your help!
