Sudden weird clutch pedal feel

[kp278]

I managed to bleed mine this morning - the first effort went nowhere as I was trying to do it without filling the bleed tank on the eezibleeder and just ended up introducing air, the second time worked a charm and now I have a normal clutch pedal with a biting point in the middle.

I did notice fluid in the bleed nipple cap when I removed it, and also on a couple of the caliper bleed nipples. I cleaned them up and retested and couldn't see any fluid coming out so hoping it's just leftover.

I bled the brakes a couple of weeks ago and wondering if I managed to introduce air. I think the reservoir did get quite low, although I never touched the clutch pedal.

I know spinnaker or chowgar had the system bled and it lasted a few weeks so not crossing anything, we shall see.

Fingers crossed for you!

Brief update - slave cylinder replaced, same problem. Next up is the master cylinder.

Thanks for sharing. Good luck with the master. Changing the master really improved my similar situation. I have a consistent clutch pedal feel low which is much better than before.

Thanks, I'm not entirely confident it will fix the issue but it's the next obvious item I guess.

I'm sure this all started after bleeding the brakes and letting the fluid drop below the clutch feed line - I'm racking my brain trying to figure that all out - surely the only fix is to bleed the system, which has been done 3 times now! Strange.

Are you bleeding it with a pressure bleeder thingy? Took my mechanic numerous ages getting it bled right when I had my last clutch done.

Hi, yes I bought one of those sealey vs820 with the pump.

Funny you say that, the Porsche specialist had trouble also, apparently they had to do it a couple of different ways.

I'm following the pdf I've seen - 30 seconds pedal to floor, 60 seconds slow pump

As Below which i think i posted in another thread .

Don't forget that both myself and Spinnaker recently had the same symptoms as you and it was indeed the clutch master cylinder that was faulty.

 

[kp278]

It should be arriving today so will report back in a few days.

DeMort yes that's the process I'm following, gives me a great clutch pedal each time, if only for a couple of days!

What would a porsche mechanic do, after replacing the slave and master, if the problem is still persistent?

Call deMort :grin:

Touch wood all still working much better for me. Fingers crossed it sorts your issue out.

Happy to report that replacing the master cylinder looks to have resolved the issue

I noticed when pumping the pedal during bleeding that the new master cylinder was silent. All the other times I bled the old master cylinder I could hear fluid swishing around - having never bled a clutch before I just figured this was normal! So definitely a symptom to look out for, for anyone reading this in the future.

Another happy customer! 8)

It is interesting as the well respected local indie i used recently said he could remember only having to do this on a few occasions over the last 10+. I think the was skeptical that a new master cylinder would fix the issue but it certainly seems to have done.
