The pedal ratio is a ratio of how much force assist the pedal is giving. You take the distance from the pivot point to the pedal pad and divide it by the distance between the pivot and where the booster/ master actuator attaches to the brake pedal arm. This will give you a ratio.
I was just hoping someone would know what these were off the top of their head.

Brake Pedal ratio is the measurement of how much mechanical assistance you are getting from the pedal. Example: a ratio of 4.1 will give you 41 pounds at the booster input rod for a 10 pound load at the pedal itself.
On the other hand,ranch beans or tacos will make you stretch and push harder to expell the gas.

Most likely some sort of safety valve will be necessary if you use a gas-assist system.

The pedal ratio is 5:1 for manual and about 4:1 for power.
Mine is now 6.5:1
