Hi. 1987 gt 5 speed. I bought this car in June 2013 with clutch nonrelease issues. I replaced the slave with a RD unit. I replaced the master cylinder with an Autozone unit. The fluid line has no leaks that I can see-it is dry and I've put two quarts of DOT 3 thru it. I ended up dropping the motor/trans and replaced the clutch (then rebuilt and swapped in a 3.4 PR while it was all torn apart), repaired the fork and replaced the TO bearing. Reinstalled everything and STILL have same issue, but not as bad. The car no longer tries to creep in gear when clutch is pressed in like it used to. Now I can get it into gear, but I have to force it and it grinds going into reverse and first. I still don't have 1" travel on the slave cylinder. Only about 0.600". I have tilted the car to the side, forward and backward, and forced plunger of slave into cylinder with valve cracked open to expel air more times than I can count. I used a one man bleeder, a vacuum pump and the petal pump method. There are no air bubbles escaping the slave valve. I'm at my wits end. Is there something I'm forgetting? Is there a master cylinder with higher stroke volume available? I've never seen any drips on the floor so I don't believe its leaking. Please throw me some suggestions before this Fiero becomes a tax deduction.
Could be the wrong master cylinder too. That was my issue. O'Reilly's have the wrong left rear brake caliper and master cylinder on record for my car (86 gt) so no matter how much I bled the system I could never get full slave cylinder travel. Wasn't until I tool it to a mechanic that knows about fieros (steve's mobile automotive) that I found out it was the wrong one. He ordered the correct one from Rodney Dickman and it has worked perfectly ever since. Clutch feels better too. With the old master cylinder the clutch was so heavy. Like if an aircraft carrier had a manual transmission that is what the clutch felt like. Seriously check the master cylinder. And also look to see if you are getting full travel on the slave cylinder. Should be about 1.15 inches. If you do get full travel then the issue is something internal to the transmission. If you don't get full travel, then the issue is the clutch hydraulics.
Thanks-I'm going to pull the pedal off so I can get a good look at it. If that checks out then maybe a different/correct master cyl. Thanks for the picture!

I did not see you mention the height of the clutch pedal in relation to the height of the brake pedal. It just about HAS to be an inch higher than the brake pedal. If it is not, you will get less than full extension at the slave cylinder, but the problem may be mechanical under the dash rather than the hydraulics.....take a look and let us know!
