Ok folks I need some advice. Looking at an '87 with the Iron Duke and a 5 speed. It's been sitting outside for 5 or 6 years. Surprisingly it doesn't have much rust, as it hasn't been exposed to salt, and it was in great condition before it was parked due to a hole in the gas tank.
I sat in it, and tried to push in the clutch. The pedal wouldn't go down. With a little more effort, it finally did. But then the pedal remained down at the floor board and didn't return to its normal position. I also noticed that the hydraulic line running the length of the underside of the car is hanging down.
Looking for thoughts, diagnosis, etc.
Thanks!

You can get a replacement clutch lines from The Fiero Store. Pricey at nearly $200 plus shipping. They take a bit of work to get them installed. A lift is essential for this operation. Rodney Dickman sells the best master cylinder and slave cylinders on the market. All total, you would have about $350 or so in parts.

Advance advice when replacing the clutch master cylinder. The pushrod will give you the impression of a bad clutch system if it's installed incorrectly. It has a curl on it at the point where it attaches to the pedal. That curl shoud be upward like so ________0

Yup. Body won't rust.

You need to look in trunk and get under and check out the steel spaceframe.

That much I know, fierosound. I've actually owned 6 Fieros. I was referring to what's underneath. Theere are a few rusty spots, but overall it's pretty good.

In addition to making sure the banjo is installed in the correct orientation, you may have to extend the pushrod by a few turns. I have never installed a "Rodney" master cylinder that I didn't have to adjust the pushrod "longer", in order to get correct travel at the slave.
Nothing wrong with that. As Charlie said, Rodney sells the best master and slave cylinders in the industry. No question. Just recognize that you might have to do it.
(OTOH, it may have been an anomaly with my clutch pedals, trannies, or clutch setup. Nothing that I own, or have owned, is stock.)

I wouldn't be surprised if the banjo purposely comes adjusted a bit short... to eliminate any chance of the master piston bottoming out on first use after installation.

For anyone installing an adjustable clutch master for the first time... you usually want as much clutch "stroke"/slave travel as possible*, but the clutch pedal should contact the floor before the master reaches the end of its travel.

I'll echo the sentiment that Rodney Dickman's Fiero parts are all top notch.

*The Getrag 5-spd doesn't seem to require as much "stroke" and can actually experience disengagement issues with too much slave travel... so only adjust the banjo length as much as is required for ideal clutch disengagement.

I have a Rodney Dickman slave and master cylinder. Stock pushrod on the master cylinder works flawlessly. It didn't come with an adjustable rod, but then I've had it in my car for probably 10 years. Maybe it was before he started including the adjustable rod.
