how to bleed a sealed clutch system?

bitburger

recently enough the clutch master cylinder failed in my doblo, the plastic plunger, which is metal on most cars failed and fiat would not supply the plunger on its own, anyway my indy got the replacement for me, which came with a metal plunger and he fitted it but had a terrible hard time bleeding it because theres no nipples on the system, he eventually got to the point that he had a working but spongey pedal and i took it back to see how well it bled out on its own, with time the pedal is back upto where it used to be almost.


my mech asked me to go online and see could i find any sort of easier method(he doesnt own a computer) does anybody know the proper way to do it, apparently its somthing that both fiat and renault do, any googling ive done just leads me to accounts of people who cant bleed it properly,

any help appreciated.

Rise up the front only, use a scissors or 4 post lift and if you raise it about a meter, and use a pressure bleeder it will bleed.
Your basically rising the slave cylinder above the level of the master

thanks for the reply, the impression i got though is that there isnt a nipple on the master or slave cylinder at all? I could be wrong on that mind you. ill get back onto him with this info and see what he says.

I cant recall whether its a nipple or the pipe partially unclips at the slave to release the fluid, surely your mechanic can figure that out.
you will still need to rise the front though

There should be a bleed nipple on the slave cylinder on the Fiats.
