Hello all.
Im trying to bleed my clutch at the gearbox end at the slave cylinder.
The hydraulic line runs to a plastic t piece that leads to the slave cylinder in the bellhousing and has a bleed nipple attached.
When i unscrew the bleed nipple no fluid comes out even though I have pressurised the line and the clutch still operates (just about).
There are some metal clips on the plastic t piece - do i need to release these?
I have tried the clio v6 forum with no response as yet but just thought I'd ask here.
Photo attached showing plastic t piece and clips.
As the car is a cliov6 it doesnt seem to be the same as any other renault.
thank you .

Some cars you may need to back bleed.

Get a decent large syringe and a piece of suitable clear tubing, then initially try and pull some fluid through.

Close it, pump the pedal, hopefully it improves, undo the valve and repeat. If you've managed to get some fluid through, you could then try and use the syringe to push the clean fluid back into the nipple

If it's a new slave in the gearbox, often it's best to try and fill this as much as possible before installation.

repeat and F about as necessary, and the odd time with pedal depressed release the nipple to see if any air/bubbles come out as in normal process.

Syringe is handy as you can push or pull fluid and also see any bubbles.

If there's pressure in the line and no air or brake fluid comes out when you unscrew the bleed nipple, the path from the line to the bleed nipple is blocked. You may need to remove and clean that T piece housing that the nipple screws into.

Also, on housings like that, sometimes it needs to be out a few turns for them to open

Again dead easy with the syringe as you'll know whether the path is open or not as you can push/pull the plunger
