Here's another method I use to bleed clutch hyd. . First , I don't like to use vac to bleed clutch or brake sytsem , sometimes it creates a vac ( air ) in the system . If you have problem getting air out of the system due hyd line routing , do a back bleed . Meaning , fill a pump or syringe with fluid then force it up from the bottom ( line that goes to slave ) then bleed it the normal way to make sure you get all the air out . This method works very well when hyd lines or pipes that route too high up or too many loops and turns .
