Hi ya

I hope all are well I am 1 year in to a rebuild of a 90 V8 1988 and i have replaced the master and slave they are brit part. I have beld the system many time and the cluch is still floppy. So i took the slave off and when we pressed the cluch the piston moved forward we pumped the cluch and the piston moved forward so we refited it and it seam to be better ie a little bit stiff at the bottom of the peddle.

If i remove the slave again and pump it until the piston comes to the front will I be able to refit it and will this work. I hope you under stand what i have said if not please ask and I will try and explain more.

is bleed nipple at top of slave ,is there much fluid coming out when pedal pressed ,when bleeding theres only 3 presses in res before empty ,master often needs bleeding first ,if you have splashing in res when pedal pumped you need a new one

the bleed nipple is at the top. there is plenty of fluid coming out I would say after three presses it would empty. The master is new i havn't seen any splashing. We did the bleed nipple up then the peddal is pressed down I take it this is correct

well if no air in system and i presume no damper near slave ,it is possible occasionally that you just need longer rod ,i have had it happen presumably clutch but it did work well after
