Help! Clutch replaced - can't keep air out of system

[Rusty_Shackelford]

Hello,
I replaced the master and slave clutch cylinders in my '85 and after I learned you have to remove the battery things went a lot smoother (another story) ... but now after bleeding the system numerous times it still:

1. Gets air in the line, especially after it sits for a while.
2. Itermittently has no pressure to the peddle at all, I looked down to see if my foot was on the peddle even. ( Don't recommend this in heavy traffic BTW).
3. Corrects itself after driving for 15 - 20 minutes - works like new ('cause it is). No doubt the self-bleeding feature kicks in. But then the peddle becomes flaccid again intermitantly.
4. Loses no fluid.

I'm at a total loss as to what to do here. Besides breaking down and taking into a shop. Which is my next move if one of the gurus here can't suggest another fix option.

Thanks in advance for your help,
RS :W

Did you take the slave loose to bleed it.. has to be held at and angle.
If it gives trouble, try pumping the pedal full stroke very fast about 50 times. Sounds crazy but it mentions pumping the pedal in the FSM to adjust the clutch. After I intalled my new slave cyl I had to do this to get it to release the clutch.

Glenn is Correct...This is the ONLY way to get all of the air out.

OK I'll try this. Been bsy working on a parking brake for my El Camino. Still haven't got it right either. Maybe, I should just ride a bicycle.

When I installed my second clutch slave (previous only lasted 10K mi.ad) I filled the slave with fluid first. After installing, had wife press clutch slowly numerous times until bubbles stopped in reservoir (trick learned at a Vette shop). Beats the hell out of laying under the car and bleeding it !
