Default Bleeding Clutch Master Cylinder

Got a 98. I need to bleed the master cylinder. It is in.

I see where the braided hose snaps into the tranny. That is done. But where do I loosen the "clutch actuator bleed fitting" which is what the Helms asks us to do.

It is the horizontal long hex shaped hollow fitting in the slave above the braided hose?? And if so what in the world do you put on it to loosen it as it is pretty darned inaccessible.

Thanks for the help,

Perry

It looks like I can get in with a 3/8ths bar. A ratchet won't fit but a bar will. Now I need to figure out what the socket size is that goes on the bleed fitting.

10mm seems too small and 12 mm too large, but 11 wont' work either. I am off to get my 6 pt set and hope it works better than 12 pts.

I believe it is a 7/16" socket and a 1/4" drive breaker bar works best.

Thanks much.

I was in the wrong tool chest. I was in the 10,11, 12 and 13 range with a 3/8ths.

I will get in it tomorrow with a 7/16ths and the 1/4 bar.

Thanks,

Perry

I could be wrong on this but are you bench bleeding it. If you are i have been told it takes forever to do. You can however buy a power bleeder for around $40 bucks and bleed it that way. Thats how i did mine and it only took me around 10 minutes to do it. And you can just do it from the top at your clutch fluid fill tank.

What type of equipment would I need? Is it a suction bleeder?

I have heard they don't work well for the clutch system.

And I am bleeding it in the car. I did the drill mod so it is not new.

Bench bleeding is very simple to do if you have a helper. I couldnt see spending $40 on something that only takes a few mins to do. I do see that it would come in handy if the parts are already on the car.

He said the parts are already back in the car. So power bleeding would be the way to go. Go to your local autozone or any other auto parts store and look for something called a vacuum bleeder pump or brake bleeder/vacuum pump. Its very inexpensive and you will be able to use it on some other applications also. Like bleeding your brake line and replacing it with nice clean fluid. There is probably a different way to do that too though.
You will probably need someone to help you a bit with pumping the brakes while you bleed it. It seems to help get more of the air out of the line.

Just get someone under the car to open the bleeder. You sit in the car to pump the clutch. Get a friend to watch the fluid resevoir and add new fluid. Don't buy these expensive ***** pumps.

If you didn't bench bleed the master you can bleed it with a friend all you want and it might not help. You can try it but you might have to resort to the mityvac anyway. I think the reason is the mityvac pulls the bubbles out the top, which is where they want to go anyway.

Bought a Mityvac at Autozone for 29.99 and finished the job in 20 minutes.

Way cool!

Yes, the parts were all ready in the car, so that made it very ez to do.

Thanks for all the great suggestions,

Perry
