I have a 383 stroker in my '85 fiero. I have a new center force clutch and (new)stock master cylinder and slave. I also replaced the pedal to a new steal one. Anyway the pedal is really tough to push in. Was wondering if any other slave cylinder either out of a newer fiero V6 or possibly a different car such as a camaro could be used? I thought with a camaro slave there would be more force to push the clutch in. If you guys have any ideas. It would be a big help. Thanks Andrew

Define 'really tough'.

Think the seat backs going to buckle and snap.... or is it just harder than the '95 Civic you drove last week?

I had to move the slave cylinder over to the wrong side of the bracket that it bolts to. Plus the rod I'm using is about an inch longer than the new rod arm that cam with the new cylinder. From what I'm been told yesterday, I should have a bent clutch fork/rod. It's really stiff, the pedal to push in. However I still have trouble getting the car in reverse. The other forward gears aren't as bad. Would having a streched cable cause these problems?

Oh ya, question what oil does the tranny take, normal tranny oil or 80/90 gear oil?

Thanks Andrew

Stretched cable? There are no cables involved anywhere (ok, except for the parking brake!).

The clutch hydraulics are pretty simple overall.
1) Make sure the rod isn't bottoming the piston into the slave.
(when it's all just sitting there, you should be able to push the rod down into the bore a little bit)
2) When you step on the pedal, make sure the piston isn't ramming into the circlip in the slave.
(have a helper step on the clutch, then pull back the boot of the slave and see where the piston is)
3) Make sure your clutch pedal isn't bent! If the clutch pedal pad is higher than the brake, you're probably OK.

Start with all that anyhow....

did you bench prime the cylinders first? The bleeding process can take a bit of time and I found pressusre bleed from the master cylinder resivour back to the slave to work best (as opposed to vacum bleeding at the slave). If your fluid has any airation in it during the process it will affect the system and that 1/4 inch of travel lost due to a minute amount of air compression in the line or cylinder makes all the difference.
