I just recently received an email from a fellow had spent $700 to "upgrade" to a McLeod hydraulic clutch, hoping to achieve reduced pedal pressure, and was quite disappointed to find it wasn't to be--here's my response as to why it made no difference, turned into a blog entry...
Could be all mental, but it seems like every hydraulic clutch I have used has less pedal effort. The only one that matched the stiffness of a cable was my Super Coupe.

All that means is that every hydraulically actuated clutch you have used has required less pedal effort than every cable actuated clutch you have experienced. You cannot compare different clutches in different vehicles as they are obviously not the same. Disengaging the Super Coupe clutch obviously had a similar work requirement.

For any given clutch, let's say the RAM HDX in my '03, and a given pedal travel, it will make no difference in pedal effort whether you transfer that effort via a cable or hydraulically--as the work (force * distance) required to throw out that clutch remains the same and we have also stipulated that the pedal throw is fixed.

Accepting same clutch and same pedal throw, the pedal force will not change regardless of how we transmit the work--basic mechanical principle nothing more.

The only ways to reduce pedal effort are to use a clutch requiring less force to throw out, or increase the mechanical/hydraulic advantage of the control mechanism--which will increase pedal travel as the amount of motion and required force at the TOB remain the same.

Are you a new owner of this Mustang? I bought an 02 a few months back and also thought the clutch was stiff.

But now I am used to it and it feels fine. I hadnt driven a stick in over 15 years before buying my Stang so I chalk it up to that. My left leg is much more powerful now after a few months.

My only complaint now is that the clutch pedal is too high.

Mine is stiff too but I agree if you had just the stock clutch it wouldn't be as stiff. I also wish mine wasn't so high it doesn't release untill the very top and it has a sqeaking TOB and I just replaced my clutch and TOB 4,000 miles ago. Sucks. I can't get it to "self adjust" by pulling up on the pedal because im guessing it being to far up.

How much free play is in the pedal? It should press down 1" to 1-3/8" before you feel the TOB start to act upon the clutch spring fingers--if not then it's too tight. If the self-adjuster does not work then you are not pulling it upward hard enough, it is broken, or an adjustable cable was installed and it was set too tight.

Here is how to adjust and manually override the self-adjuster...

Does it have the stock clutch quadrant? Snap a pic of the pedal assembly, above the gas pedal, and we'll know what you're working with.

Some aftermarket quadrants have a quicker ratio than others, which affects pedal feel.
