***CHOOSE YOUR KIT BELOW BASED ON YOUR FRONT AND REAR BRAKE SETUP***

Each KIT below comes with a master cylinder that matches the bore size to your front and rear brake setup. Matching the correct bore size to your front and rear brake setup gives the appropriate amount of volume on the first pedal stroke and the maximum amount a line pressure with the least amount of pedal effort.

Please contact use if your front and rear brake combination is not represented below so we can suggest a KIT that will perform best with the brake setup you have.
