[Fot] Clutch Hydraulics Revisited

[Robert M. Lang]

Hi,

I scanned the FOT archives quickly and maybe I missed seeing anything 
definitive on the subject. My "issue" is that since I switched from the 
stock TR6 clutch M/C to a Tilton unit, I've been having problems with 
clutch disk / flywheel glazing (and subsequent slippage). Now, the problem 
could be that I'm leaving my clutch foot resting on the clutch pedal, but 
I installed a dead pedal a while back - perhaps before the latest clutch 
installation - and in my videos, you can def hear what is either wheel 
spin or clutch slippage when I floor it.

The Tilton clutch M/C that was installed has AN3 fittings and the stock 
setup is AN4. Is there any chance that the smaller hose / pipe can 
restrict the hydraulic motion in a way that can effect rapid clutch 
release?

I'm next to positive that there's nothing stupid going on here, like a 
residual pressure valve or something like that. I'm 99% sure I can push 
the slave's pushrod and cause fluid to back-flow into the M/C reservior.

This is really annoying because the original clutch setup (a 69 M/C with a 
used B&B PP and all "stock" stuff) lasted for 6 or 7 seasons and the new 
setup(s) only seem to last 1/2 season or so. That's like 50 autocross 
launches, max.

BTW, the dead pedal is so awesome that I forget to push the clutch in when 
I start spinning. This has led to some pretty impressive 180's!!! Gotta 
work on that aspect of my driving, I guess.

Regards,
rml
