My turn for a clutch problem - Astra H
« on: 24 May 2018, 11:24:30 »

So the missus' Astra cluth has been problematic recently with getting in to gear first thing being intermittently difficult.  I noticed the brake/clutch fluid was very old and flushed the entire system.  Some of it was nearly black when it came out.  This resolved the problem but it came back with a vengeance last night.  The missus popped out and the clutch failed entirely, being impossible get in to any gear with the engine running.  I met her and noticed the fluid was at 'low' in the filler reservoir so I started in first and rev-matched it to get home.  Once the reservoir was topped up and the clutch primed a few dozen times the resistance in the pedal came back and it worked again.  I did notice that the pedal get a little spongy after a few minutes if not used, but once a full press and release is performed the resistance returns and all is well again. 

Everything points to a leak but there are no tell-tale marks on the driveway to indicate fluid is escaping.  Therefore it might be the master/operating cylinder.  I have yet to get it up on the ramps to get a decent look underneath but before I do what the thoughts/advice from the learned masses?

Any evidence of fluid either in the bulkhead insulation or under the carpet?

Not that I noticed, but I didn't check.  I will have a look when the swmbo is back next.

Passenger well is dry.  More research indicates that it is most likely the slave probably letting air in and occasionally dumping a load of fluid (ie not a constant leak.  This can be caused by the DMF bearing having gone causing damage to the slave bearing seal.  At least that is what a local garage has said.  Best case scenario about 400quid for the slave and clutch, or double if the DMF needs to be replaced.

Ouch.

Makes the traditional two bolts and a hydraulic connection 25 external slave look like a good idea doesn't it? You know, the sort you could change while the kettle boiled?

Yup as soon as I read that it had a concentric slave I uttered something which would be filtered out by the forum's software  :-[

Apparently to drop the GB you also have to drop the subframe.

Likewise with the Astra G before it. It's not such a difficult job ..... remember to slacken off the bottom of the steering column  :y

It turns out that the fluid or grease from the flywheel was leaking on to the starter motor so that needs replacing too.  It can be tough to start sometimes so that fits the overall picture. 

At least the flipping mechanical roof still works (rare) ;D
