If you are operating one caliper on the front and one on the rear I would try 3/4" bore master cylinders. If you have two calipers front and two rear then I would try 7/8" bore size.

Hi, what is ratio?? I see 7 to 1 systems and 8 to 1 systems. what's the difference ? What one reacts faster What one breaks more with less effort ? Does the ratio effect pedal travel ? My application is to retro fit a heavy car used in dirt racing. Please let me know. Thank you, Dean

The pedal ratio (in this case 7:1) refers to the length of the pedal arm from the pivot point to the pedal pad compared to the length from the pivot point to the connection of the master cylinder. The higher the pedal ratio the longer the pedal length and/or shorter the length from the pivot point to the master cylinder connection. Higher pedal ratio will require less effort to stop but also increase the distance that the pedal has to travel. The 7:1 ratio of this pedal assembly works well in dirt oval track cars.
