Hey there all. I just fixed my clutch again!!!

List of problems with it over the years:

1) Fork bent/broken...welded some plate to it to stengthen the original design

2) Master leaking...replaced with Fiero store equivelent

3) Slave leaking....replaced with Fiero strore equivelent

4) Pedal bending, replaced with steel equivelent

This time, it seems the master cylinder pushrod decided to bend at the change in angle.

Something strange though;even when I straigtened it out it seemed that I wasn't getting full stroke out of it. That is, the pedal could go further to the front than the linkage had length for, effecitvely shortening the throw. I had to push in the clutch pedal about 1" before the linkage would slide over the pin on the clutch pedal.

Anyone noticed this? When it slipped over the pin the clutch pedal was just a shade lower than the brake pedal.

So, I welded a .75" extension on the master cylinder pushrod and welded plate up to the angled section of the pushrod to stengthen it. The result? A clutch smoother and easier than I have ever experieced before. It used to be I had to floor the cluth to release it, now it releases somewhere near mid stroke and I am very happy about it!

Anyone else noticed this descrepancy, or perhaps is my setup bent somewhere?

With the adjustable banjo from Dickmans you can adjust simular to what you did...

But...

If you start off mid stroke, you'll cover up the compensation port in the M/C. So, if you ever have fluid loss in the slave, you'll never allow the system to top itself back up from the reservoir.

It wasn't starting in mid stroke though, that was the thing.

The master 'plunger' is fully reset way before (1") the pedal was in it's full out position...the fact that there is an adjustable 'banjo' (Who knew there was a word for this thing) answers my question. Anyone suffering clutch stroke issues not related to leakage/component failure may want to check out this option...simple to diagnose...pull off your 'banjo' and see if the pedal moves toward the driver before hitting the stop. If so, you are being robbed of possible travel.

The only caution would be to watch out for extreme cases where a large adjustment would lead to bottoming out of the master plunger when the cluth pedal is fully depressed.
