How is clutch pedal ratio measured?
Pedal ratio is the amount of leverage your clutch pedal exerts over the master cylinder. On average, clutch pedal ratios range from 5.0-7.0:1. To determine the pedal ratio, measure the pedal pad to the pivot, then measure from the master cylinder rod mount to the pivot and divide the second measurement into the first.

How to measure and adjust your clutch pedal?
The formula is X/Y=Ratio. For example, your stock clutch pedal is 14 inches long (X), with a pickup point measuring 4 inches from the center of the fulcrum (Y). 14/4=3.5, which is 3.5:1. While this may have worked for the factory manual linkage, it is about half of what it needs to be for a hydraulic set up.

I put the bolt into an electric drill motor, which allowed me to grind the piece on a stone and a piece of coarse sandpaper to get a nice radius. I used 5/8-inch OD chromoly tubing to build the linkage.
