Clutch problem?

^^^^^ +1 with Fred

There is a spec for how far the slave rod should move out with clutch pedal fully depressed. I THINK the slave should extend .53 inches with pedal fully depressed.

Someone feel free to correct the .53" number I have stored in my old guy brain if I am wrong wrong!!

Not sure why the only subject is the hydraulic components.  If your pressure plate is fatigued and some of the fingers have failed it may not have the strength to pull the plate away from the clutch all the way.  Also, you may consider the clutch fork.  Definitely easier to eliminate the hydraulic components first.
Thanks for the reply Fred, i will look into that too

Thanks Jeff, I see the fork moving and the stuff on the inside too..it moves about half inch maybe.

Might as well..who know when was the last time that it was changed.

NOTE:

The Removal and Installation instructions in both the original 1987 Ford and Haynes shop Manuals tell you to remove the clutch master cylinder BY TURNING 45 DEGREES CLOCKWISE. This is INCORRECT.

To remove, it is the OPPOSITE—turn 45 degrees COUNTER-CLOCKWISE. To install, turn it 45 degrees CLOCKWISE. You will find it MUCH easier to place a suitably-sized socket on the end of the master cylinder, to aid in turning it (I can’t recall the size). It is a VERY tight fit.

I know this is wrong because I spent an hour or more trying to install it the manual’s way, before I finally tried the other way in desperation (we do learn by doing). The 1988 Supplement to the 1987 Ford shop manual corrects this issue.

I have had the same symptoms as you many times, and it has always come down to the hydraulic components. There was even a time a brand-new slave cylinder gave those symptoms only hours after it was installed, placing it near the bottom of a probable list of causes. It was proved to be faulty.

Good job! The clutch bleeding is kind of a PITA, IMO.

Happy to help! There is a lot of knowledge here, some of it “book smarts” but most of it actual repair experience.
