Clutch bleeding??

[daviewonder]

Hello All

I have a V6 coupe on an R reg that has the sealed clutch slave and master system. Over the past year the clutch pedal has been getting worse and worse. I have to pump the pedal quite a few times to get it in gear most of the time and the car tries to creep forward with the clutch fully down, it's especially worse on cold days.


I've had a look at diagrams of both the early and late systems and none of the parts are interchangeable as far as I can tell.

Has anyone found a way to modify the system to enable it to be bled?

I've considered adding a reservoir in place of the sealed fluid pot and drilling a small hole and tapping a screw in the back of the slave cylinder to to allow it to be bleed.

The system is no longer available from Peugeot and when it was it was nigh on £400. Anyone have any ideas as I don't fancy a second hand one. I don't want the Coupe to end up on the scrap heap because of this.


Thanks, Dave (What were Peugeot thinking when they designed this?)

I know you aren't looking for a second hand set up, but as a last resort, you could try giving Adrian Bingham ('ade1122' on the Coupe forum) a buzz....he'd be sure to sort you out a complete set up. He won't rip you off either!

Here's one Ade's got for sale:

You really don't want to pull on that thread, trust me.

Thinking? Who said they were thinking?

Do you know for a fact that none of the parts are interchangeable? It might make your plan easier if, say, the slave fits (even though you'd have to get a hp line made...)

Question is, what's gone wrong with yours? I think normally they loose all the fluid, which would rather imply that the seals in the slave cylinder have gone. However, if you're pumping the pedal it probably means the seals in the master have gone - either way I reckon if the seals one end have gone the seals at the other won't be far behind.

I guess if I were you I'd pick one up off Ade so my car was still usable and investigate the old one with regard to resealing & introducing a little sanity to it at my leisure.

If they were thinking that it'd make replacement a piece of cake, they'd be bang on right. Swapping hydraulics between two cars can easily be done in 10 minutes!

However, since they're now all knackered and irreplaceable, I'd suggest "upgrading" to the D9 discrete components. I've not done this myself, but as far as I can tell, all you'll need is a master cylinder, slave cylinder (only £16 from dealers last time I looked - cheaper than anywhere else! ), pipework, and a new brake fluid reservoir. Hopefully the master cylinder bulkhead fitting is the same...

Oh, and a hell of a lot of patience and paper towels for bleeding everything

Hopefully the master cylinder bulkhead fitting is the same...

That's the bit I've been wondering about, the pedal bracket is a different part number so maybe it won't be that easy

What it needs is a guinea pig...

or zip ties...

Turns out all you need to do is open up the small pot on the bulkhead that says 'Do not open' and pour in some fresh fluid. Jobs a gooden and the clutch works like a charm ;)
