Technical Looking for hydraulic clutch linkage, see picture.

I'm looking for a source of something like the pedal linkage in the picture. Without buying a $250 kit. I already have the Wilwood master, slave, hose, etc. Something from the junkyard would be fine. The clutch is bled, no bind in the linkage, just very hard pedal pressure. I did move the clevis mounting point down a little so it would be inline with the master. Maybe a simple dog-leg piece would work, something to attach to the original mounting point on the pedal. Also look at the picture of what I have now. Thanks!

 

Could your clutch fork be too short - if you have enough slave cyl travel, maybe a longer fork arm would give better leverage/mechanical advantage.

 

Is it feasible to shorten the brake pedal arm above the pushrod, moving the pedal pivot closer to the pushrod and improving the pedal ratio?

I do agree with no55mad's thought about checking fork length as a way to accomplish improved leverage......just offering an alternative if that doesn't work out space wise.

Just 1 more reason I like mech. clutch linkage.....

I can move the rod over on the fork. This is a Chevy truck cast iron fork. I'll have to space the slave off the bell housing, not a problem. I have good motion at the arm but still have to adjust the pedal stop under the dash. I have a good inve$tment into the dealie right now, not ready to give up on it yet.

I'll also look at the pedal ratio, forget how much I moved it down to where it is now. Thanks guys! I'll get back into it over the weekend.

 

Anyway, I now have a clutch pedal that works so well, I can push it by hand and have good motion at the fork. Pulled an almost all-nighter last night.

Things done: Bought rod ends (in 1st post above) at a local speed shop. Made up a link arm from mild steel (.380 thick). Moved the pivot point up to the stock position level on the arm. Located a fixed clevis (Speedway item) below the clutch master. Fabricated a 6061-T6 aluminum offset clevis to attach the clutch master rod to the link. This will be re-made in steel.
Things to do: Make sure the clutch releases and engages smoothly. I can still move the slave over on the fork if I need more travel.

 

Things to do: Pictures?

 

I'll take some later if I dive into it, it has to come apart one more time. CAD drawings are being created for the parts.
