Constantly bleeding clutch - inconsistent pedal

Hello all,

Having a bit of clutch trouble and hoping you can help me - I've bled the clutch a few times now and it seems to manage to get some air in again and again.

It's the typical thing - very light for first bit of pedal travel then you can feel the difference at some point on the way down. This point seems to vary with how much I use the brakes (I know the systems are linked) and sometimes it's difficult to change gear because it activates so low in pedal travel.

I'm sure I've bled the clutch correctly but is there something I'm missing? I'm going to try bleeding brakes & clutch later to see if that helps as I think the brakes might be affected too (not really feeling any difference at the pedal here but I reckon it's worth a try)

Or am I clutching at straws and need a new master cylinder?


P.S. I'm certain I'm not suffering from any leaks.....

Girlie Fiat driver: "You got a new car?"
Me: "Yep and I love it"
GFD: "Alfa though.... Aren't they supposed to be unreliable"
Me (looking over her shoulder at her Punto and laughing inwardly): "So they say......"

lack of clutching at air more like!!! (get it!!). I think you've hit the nail on the head. Master or slave would be my first though really.

Yep! seals in one or both could be failing. Normally the slave gives problems first, master later. It may have a tandem split cylinder reservoir for the brakes and the clutch, but the systems are separate.:

When you bleed the clutch are you pushing the pipe back in before you lift the pedal each time? If not it can suck the air bubbles back into the slave from the feed pipe as it doesn't have a return valve.

Or try one of the pressurised bleed systems like Gunson that will force fluid through without touching the pedal.

yeah - I've always been closing it off before pedal return....

So now I'm looking for a slave cylinder.... Anyone got any guides on how to replace this?

Sound,s like slave cylinder, unfortunately unlike 155,s which they decided were to easy to fix they put the the 156 slave cylinder inside the gearbox which is probaly why you can,t see the leak. gearbox opened up I,m afraid, might as well do clutch at same time. Hope I,m wrong and you find a easy fix.
