Factory clutch?

Did you try a vacuum bleeder? I have had great success bleeding it with vacuum as the factory procedure calls for, and seen a lot of people have issues when trying to bleed conventionally, although there are many who say it can be done without issues.

I made a simple stopper for the brake fluid cap opening and stick a little hand vacuum pump into it, pull down 20in/hg and leave for 5 min or so, then release and pump the pedal slowly 10 times, then re-apply vacuum. I do this 3-4 times while i'm buttoning up the top of the engine bay at the end. Once I get a nice firm pedal, I am done bleeding and never have to touch the bleeder screw or have a second person.

 

Second using the vacuum bleeder. The bleed screw is before the slave so you can easily trap air in the slave. Vacuum should do better at pulling it out.

 

another method ive had work well on various hard to bleed clutch systems is to very slowly push the pedal down, hold it for 5 seconds then release it quick. the theory behind it is while slowly pushing the clutch down the air bubbles sort of stay put in the line, and while holsing they will move back to the part thats trapping them, and releasing it quick will "pull" them back towards the master cylinder, and they eventually will get worked out.

 

I am having trouble bleeding mine as well.Could the bleeder screw be in a worse place????
I will try the above method.Worth a try.Thanks

 

Did you replace the master clutch cylinder? If you put in a brand new clutch, it makes sense to replace the MCC right along with the slave cylinder.

When I purchased #3, the clutch pedal released right off of the floor and it was mushy garbage. I replaced the master clutch cylinder and it's good as new. No amount of bleeding is going to save an internally worn MCC.

 

I am buying a vacuum bleeder today.Hope it works for me.

 

how did you make a stopper please show me what you used

 

Go to Amazon and look at rubber stoppers, they should list the dimensions and fine one that fits. Then take a drill bit to make a hole the bleeder can pull vacuum on

 

Or go to a junk yard and buy a second brake reservoir cap and modify it to hold pressure.

Or just spend the extra coin on a ready made one:
And as an FYI, I've never pressure or vacuum bled the brakes or clutch on this car, and I've had great success with having good pedal feel. It becomes a two person job though, but it's simple.
