Question Replacing slave cylinder

Whenever I park the beast at night and get in the next morning, there is little pressure behind the clutch. Once I get into gear the pressure comes back like normal. It might also be helpful to know that I park on the road, which has the truck tipped toward the driver's side.
When I parked the other night (facing the other way, tipped towards the passenger side) and I lost all pressure. I couldn't even get into first gear.

A friend told me that it sounds like the slave cylinder might needs replacing. Any second opinions? And how hard is it to do?

You should have a reservoir. Have you added fluid?

If the slave is a problem then you should find that it is leaking. Replacing the slave is easy, the master cylinder is another story.

My master cylinder leaks right now. I have to pull the clutch pedal up, it siphons fluid from the reservoir, I add fluid, and I'm good to go unlit it leaks some more. I've been too busy/lazy to replace it.

The reservoir is full. And I haven't noticed any fluids leaking.

I do not have a definite answer for you.

Thinking about hydraulics; If there are no leaks then the only way for pressure to leave the system is to slip past the master cylinder back into the reservoir.

Air in the system will cause similar problems, but that's not something that just happens. There should be a cause.

If the slave cylinder leaks it is usually into the bellhousing.

Now the pressure comes and goes while driving. If there is air in the system, how can I fix this?

Sounds like biteing the bullit on this one is the only answer. Replace the slave and if that doesn't do it replace the master. I did a guys Amigo slave first and it had no leaks but couldn't get preasure to the new slave. I replaced the master(sucked) and it was all good he was extremely happy because he thought he was in need of a clutch. So the moral to my rambleings is .........start with slave then master.

Replaced both today, still no pressure I made sure that I bled them properly, and scanned along the line for leaks, but didn't see any. A couple of friends are saying that the pressure plate sounds like it's shot.

Well that blows. Well once you replace the clutch you will be good to go with trouble free driveing at least in that area.

Sometimes that is all we have to hold onto and to justify the expense.LOL Just make sure if you do the clutch, cover all your bases, resurface the flywheel, pilot bearing, release bearing and rear main seal it might not be a bad idea to replace the input shaft seal on trans being yo will have it out too.
