Got the beasty up & running and seems to better than I thought it would be.
The vacum hose has been blocked with a bolt so the vacum assist must have shit itself somewhere. I know there is valve somwhere in the vacum line, how do I test this and is there any other test I can do before pulling the unit off.
Had one pack up once before and bought a kit, turned out it was only the small seal at the front & behind the clutch master cylinder. But you cant buy just this one seal or so I was told, seems to be the one that goes all the time.
thanks

If it was the vac pump surely the brake booster would be playing up too.....like it is on mine : ) I also couldn't find any info on how to test and isolate the boosters from the system. My clutch is stiff regardless of motor revvs and I would never of known they could be better if I hadn't had a go of one that worked...be keen to hear how you go with the fix

Again it was the front seal on the booster, three different GQs that I have a problem with come down to this little bugger and I have'nt been able to buy just this seal, $80.00 for a full kit BUGGER.
If anyone is in the seal line, this is the one
Bendix # 221-24100 EZ or E7
Would be great if we get a few of these as it seems to be the only bit that shits itself

Sounds right, same thing happened to me - i went to a clutch place and they said it would only be a small rubber seal as in their experience with GQ's thats all it ever is. I left with instructions, a $20 new seal and some rubber grease, it took me about 40 minutes on the side of the road and problem fixed. I went back with some beers for the guy and got another seal to carry as a spare.

LOL...I must have got lucky and just struck the right guy at the right place at the right time. I wanted to get a couple more but he said no as they had limited stock and they come in from Aust.johno wrote:How the hell did you get a seal, everywhere ive been they reckon you can't just buy the seal you have to buy a kit.
Mate you are anywhere near this bloke can you grab me two seals and I will transfer the money direct to your account. I'm in N.Z. and can't find any place to help..

As far as testing your vacuum goes - he did tell me to remove vac line from booster while engine running, if the vacuum tries to suck ya finger down the rubber hose then your vac is ok and IT WILL be the small rubber seal inside the clutch booster.
However if there is no sucky the finger down the hose feeling then the fault is with the vacuum itself and then it becomes a bit more serious and not so easy to fix on the side of the road.
When replacing leave clutch fluid pipes attached to the slave cyl and move it aside carefully, that way by not disconnecting the pipes you don't have to bleed the system afterwards. Hope this helps.
I'll try and upload a pic of the seal.
