why can't i bleed my clutch? pics

[AndrewD]

hope so

Exactly like that. And with leaves in or out bubbles travelled back up to nipple. Hence my question! Bled a clutch on a vmax before and it was a piece of piss. This one however is starting to bug me.

I use one of these...

BLEEDER

Makes short work of brakes etc...

Your nipple is leaking, I think.

Hmm, try a google image search for leaking nipples!

That's why I was comparing to the ones from Shaw engineering.

If you don't have an airline for the self bleed it a feck off big syringe will also do (try a horse vet if you struggle).

From experience, I learned that the best way to bleed a circuit is using a vacuum pump (I have the plastic mityvac unit). Using anything else will draw air trough the bleeder threads.

Hold the clutch bleeding unit up or secure it to the top of the subframe with a cable tie and air can't get into the system.

You can self bleed through gravity the same way, no need to pump it or use vacuum unless you've broken into the circuit.
Hold it up and fluid rises out through the bleed unit without doing a thing.

The best way by far, this eliminates any chance of air getting down the nipple threads

I zip tie it to the pillion peg mount (so its above the slave cylinder) and give the lever a gentle squeeze (not all the way back to the bar) to speed things up a bit.
I still have the black adaptor and screw a nipple into the end with a bit of tube attached. As its a 10 min job, I do it every year and therefore never have a problem with the grub screw.

Ok this puts a different twist on the problem. Sounds daft, but when you try to bleed the clutch does the fluid in the reservoir actually drop?

Air in the system cannot cause the clutch to slip. However if the fluid is not dropping this may be that the fluid return hole in the master cyl is not being exposed. Look in the reservoir and there is a hole in the bottom with a shaft exposed you should be able to see a full hole in the shaft. If not you will have the air bubble just being pushed back and forth, this would explain the biting point being at the end of lever movement and could very well cause clutch slip. Hope thats of some help

Air in system so bled it,pumped clutch a few times, held it to bar and cracked open nipple (with clear pipe on and end in fluid) noticed small bubbles travelling back into nipple when i had the nipple closed.

I don't think your bleeding it properly from the above
