So I installed a new clutch pack and then the master or slave cylinder went out. Clutch pressure plate was really weak so I suspect new pack caused extra pressure on master/slave and seals gave way. 1995 truck with original master/.salve.... Anyway, I have read that bleeding these are a real pain. Any suggestions would be appreciated.

Why did you not make sure the new clutch disk was correct? Should have inspected the flywheel better, eh? Where is the leak at? The throwout-bearing or the Master Cylinder? No it's not hard to get all the air out of the system, but I don't think that you have done that.

Truck ran fine for a couple of months after pack installation. All was new except master/salve, and FW was resurfaced. My slave is external and not inside bellhousing. It has traditional fork.

Its just a matter of gravity bleed or bleeding it out with a pump.At the age of your Chevy, you might need a new M/C as well, but try bleeding it out first.

Master and slave are new. Just need to bleed. I am hoping just like doing a brake line. There is only one bleeder valve and it is on slave. THX

Crack the bleeder on the slave and allow to gravity bleed.

Test pedal - if it still feels like there’s air in the system, set fluid level to minimum and leave cap off, then remove the slave from its mount, hold it vertically so the line is on top, and slowly depress the piston until it’s fully retracted. This will force air back up to the MC and out the reservoir.

A helper to monitor the fluid level and air flow is useful but this can be done by yourself.

Mount slave cylinder and pump the clutch a few times - if it still feels like there’s air in the system, repeat the process.

Thanks to all. Mission accomplished!
