thas bout the just if it it just wont bleed ... new cluch new lines new cluch master cylender but it still wont hold a bleed but if u pump it it will build presure

 

how are you bleeding it? the best way is to have everything empty and bleed from the bottom forcing fluid from the bottom to top pushing out all air bubbles. i have done tons like this on transport trucks and it is the only way to get it perfect. i have seen guys bleed a clutch for hours trying to get it right

 

Another method I used for years when the standard hold-the-pedal-down-open-the-bleeder method epic failed was to follow up with leaving the clutch master cylinder cap off/bleeder closed/engine off...and pump the pedal real fast for about a minute - wait a minute and repeat.
