I remedied that by making a new rod out of a 1/4 socket extension. I have tried three different tilton master clyinders with bores from 1/2" to 3/4" and still the same extreme pressure. next it pushed the bolts wich hold the master cylinder thru the fiberglass firewall, Obviously something is not right.

I am using a tilton hydraulic thro-out bearing and a 11" center force clutch with a diaphram style pressure plate.

Any help would be greatly appreciated!!!! Thanks, Dave

What would be a better set-up to use in my car?????
Your clutch must be a racing clutch on the street, What I have done is convert to a smaller master as that will give you more applied pressure at throwout bearing than a big master. The other thing that works is convert to a pusher throw out instead of a tilton puller,This solves a lot of problems and is smooth to operate. Contact me if you have any more problems. I mount the pusher on the side of the bell housing and alignment must be close or you will get too buch wasted motion from slave cyl.
