What effect does adjustable master have Did clutch swap and bleed and still have issues with clutch. Set adjustable master as close to stock length as could thinking that my zoom clutch came with a stock type pressure plate.
Clutch disengages/engages close to the floor and is hard to shift while sitting still into all gears, but especially reverse.
Want to move engage point further to the top and hopefully get a little more slave push for better disengagement.
Do I Lengthen or shorten rod? My guess is lengthen, but don't want to spend 4 hours figuring out the facts, so any help would be welcome.
Thanks

Your Zoom clutch is set up to use the original pushrod length. If you lengthen the pushrod, it may preload the release system and reduce the clamp load of the clutch. It may also over stroke the diaphragm spring, damaging the clutch.
The first thing to double and tripple check is bleeding the system. Can you explain how you bled it? Does the clutch pedal feel like it is going over-center. (this is the feeling of the clutch pedal getting stiffer to a point until it actually begins to get lighter. It should begin to go over-center about half way through the pedal travel. If this happens closer to the floor, you probably still have air in the system.)
Here is another method of bleeding these systems:
Get your hands on a Mity Vac or similar product. Obtain a rubber stopper sized to your clutch master cylinder reservoir opening and pierce a hole in it so that you can fit tubing through the rubber stopper into the reservoir. Don't let the tube dip into the brake fluid. Connect the other end of the tubing to the Mity Vac and pump to about 15-20 inches of mercury. Hold this vacuum for a minute and release. Check reservoir and refill. Repeat if nessicary.
If you have a normal over-center feel there may be another problem. It is possible that there is problem with the disc marcel being over expanded during the riveting operation and causing the cushion of the disc to exceed the lift of the pressure plate. This causes poor release. (the marcel is the wavy back-plate under the facings that provides easy long engagement instead of a short harsh engagement.)
Hope this helps.

Well, here's how we did mine recently...
Adjust the rod in.....then thoroughly bleed the system.....
THEN adjust the rod out, until the clutch pedal feels right, for you...
Not sure if its the right way, but its what worked it
