Am I doing this right?

[90jurassic2]

85 Ranger. Has a 5TK in it. Just replaced flywheel and slave cylinder and did a clutch kit. When I try to crack open the bleeder on the slave it feels like its stuck shut. Maybe I'm being a puss and not trying hard enough?

Well it has to be opened so..............bummer if it is defective and you have to replace it

Ok so I was being a puss. Got it cracked tried bleeding it and now it's leaking. It looks like the line isn't going in all the way.

 

[90jurassic2]

Got the line in. Now there's fluid dripping on the ground. Looks like from the bottom of the bell housing. Anyone have any ideas on what's going wrong?

EDIT: The leak stopped. I've been pumping and cracking the bleed valve and I have no pressure on the clutch pedal. I've tried numerous times to build up pressure and I'm getting nothing.

If you have all the parts installed properly in the truck and you are now trying to bleed the system you did it wrong.

I've been reading about air getting trapped in the clutch master cylinder. Could that be causing this? It's an intermittent leak. Sometimes it's there and sometimes it's not. What are the chances of getting a bad slave? I'm pretty certain I put everything in the right way.

 

[adsm08]

Chances of getting a bad slave will vary widely by brand. Call it 50/50.

Air trapped in the master will not cause a leak.

Finally got it bled. I don't quite know how, but it works pretty darn good. Thanks for all the replies.

Slave Cylinders have to be "Bench Bled" which means you bleed it before installing it. I didn't know that before I installed mine, and a year later I was replacing the Master Cylinder.

That being said: The reason you have no pressure behind the clutch is because there is a big air bubble in that hydraulic line between the master and slave cylinders. Im assuming you have everything put together already. If so, I have some good news. It can be (what I call) "Reverse Bled".

To Reverse Bleed, you need to pump the hydraulic fluid (DOT3 brake fluid) in through the bleeder and up to the master cylinder. This will push the bubble up through your master cylinder and into the reservoir, then into the air where it belongs.

The pump thing I used looks like a paint gun with a hose attached to the "spray" end.

With all the trouble folks have bleeding this system it seems to me that this is the way it should be done.......

If you do not have the tools to get a reverse bleeder there is another method you can use.

Gravity bleed the system by leaving the cap off of the master cylinder, opening the bleed valve on the slave cylinder and pushing and holdind the pedal for about a min. The fluid is heavy enough to push all the air out of the system. This also work with bleeding new brake calipers.

Is the slave external on an 85? If so, detach it from the bell hsng and bleed it whilst pushing the arm. If it isnt, like the Rat's, a gravity bleed was how I did it with the MC loose and pointed down. All of this was in the directions I got with the new MC and slave I put in. I'm a cheap SOB,I don't like buying tools that will rarely get used, so I use gravity, its free

Wrong. Master cylinders have to be bench bled not slave cylinders. Bench bleeding the master is really easy. This video shows you exactly what to do. https://www.youtube.com/watch?v=HgNTDGwcjZc Once you got the master bled and installed attach the high pressure line to the slave. Open the bleeder valve on the slave and let fluid run out but make sure to keep adding fluid so you don't run low and trap air back in the system. Run a couple of reservoirs worth of fluid through it and then tighten the valve. Your all done.
