This is for my '88 coupe

I put a clutch in less than 15,000 miles ago, and it's getting hard to get it
into first and reverse again.

I can only get about 5/8" travel out of mine, is that about right?

With that little travel, I'm surprised that it is working at all.
You should have about 15/16" travel in a healthy system.
Give it a good bleed again and see if it improves.

Bled it again, still only about 5/8 of movement at the fork.

What's next?

Did you get any air?
Look for internal leaks in the master and slave. Also the supply line.
Make sure the banjo rod is OK and not bent.
Is your clutch pedal about an inch higher than the brake pedal?

I got air, but then let the M/C run dry and it sucked air again.
No leaks anywhere along the lines, Don't know how to check M/C or slave,
if clutch pedal is held for a long time the clutch fork holds it's place
(no slow release of fork as long as pedal is held to the floor).
Banjo rod is straight.
Clutch pedal is the same height as the brake pedal (against its stop).

Edited, because i can't spell staright. (darn! did it again!)

Here's your problem. Your clutch pedal is bent. The clutch pedal pad should sit an easy 3/4" higher than the brake pedal when they are fully released ( at the stops).

You'll never get all the air out without the clutch MC piston retracting the full way, nor will you have enough fluid movement due to the piston not travelling the correct amount.

replace that clutch pedal, and all should be ok.

Also make sure the loop on the banjo is pointed up.

EDIT: because I can't spell either..!

Banjo is pointed up.

Pulled the clutch pedal (it is steel) and it is straight.

Made an adjustable banjo: I cut mine in half and machined a "sleeve" with 8 set-screws
that now joins the two halves of my banjo, this allows me to make my banjo longer or
shorter by simply adjusting the distance between the two halves of the banjo inside my
"sleeve" and then tightening the set screws. Now i can bottom out the M/C with no problem.
Still 1/2" of travel.

Don't take this the wrong way Ed, but those adjustable banjo's are just a band aid to try and make up for a problem.

You should play with your banjo if you don't want to replace the pedal, you need to get that MC piston in the right spot and get the correct amount of MC travel after it's set up.

Personally I'd still replace that clutch pedal, you could be forever trying to get it work right with an adjustable banjo.

I believe you have a simple problem, but are multiplying it by not replacing that pedal.

Jelly: All suggestions/advice/oppinions are welcomed by me.

The reason i made an adjustable banjo. I thought that even if the pedal is bent,
(which i don't see) I would regain the "lost" M/C travel that i may have lost
over the years with the normal wear and tear on the pedal, bushings, original
banjo, and M/C. My pedal now sits (at rest) a good inch higher than
the brake pedal, and as i stated above, i can now feel when the clutch
M/C bottoms out.
I have bled this thing (almost 2 quarts of fluid thru the system) using
V-8 Archie's method and still have about 1/2" of travel at the clutch
arm/fork.
I have no leaks anywhere in the system (checked behind carpet etc)

Thank you, so much.

Ed
