when adjusting the slack in the clutch pedal how much free travel should there be and is it better measured using the foot or the hand? might sound like a dumb question but i've been told to do it both ways. thanks.
Assuming you still have the factory clutch quadrant and adjuster pawl you can "pull" up on the clutch pedal and you will hear a clicking sound if it needed adjustment.
Most quadrants tend to get old and brittle and the pawls break so people replace them with an aluminum quadrant and firewall adjuster to achieve proper adjustment.
With my stock quadrant and cable I would have to have the pedal to the floor to get in gear and it would start to grab as soon as I let it out.I installed anadjustable cable,adjustable firewall adjuster,and billet quadrant and now It grabs about an in and a half off the floor.I have heard that if you get a firewall adjuster and a ford cable that it will work too.Mine came with the adjustable cable so at least now it's "fully" adjustable.
there are different methods. some folks dial a little preload into the cable (zero slack in the cable and then tighten a little more). some folks like a little freeplay. i keep around a 1/2 to 3/4" of freeplay (measured at the pedal) myself.
i actually check it by pushin on the pedal with my hand (only because i can feel the freeplay better with my hand than my foot).
Factory quadrant and cable, needs to go. Get a good adjustable quadrant kit. Adjust cable (either with the cable or the FWA) while running while watching the TOB and when it stops spinning it is adjusted properly. edit: imporper adjustment can shorten the life of the TOB.
I bet it would be because you would have the change the pedal, install a clutch master cylinder, as well as a slave cylinder. I doubt it would be worth it, but thanks for letting me know it's out there.
