Finishing Lines Billet Adjustable Brake Pedal is not just another beautiful billet aluminum part. It serves a valuable functional purpose with clever engineering to fill in the missing piece of the puzzle to your modified brake system.

This pedal assembly allows you to optimize your brake system changes and upgrades by adjusting your brake pedal to either 6:1, 7:1 or 8:1 vs the OEM 4:1 ratio.

This is intended to be used with booster deleted manual brake systems only. You must have an aftermarket master cylinder such as Wilwood/Tilton with a 5/16"-24 push rod to utilize this pedal. This is not for bolting into a booster type OEM brake system. Do not attempt to use it for that purpose.

The details and explanation:

For many years it has been popular to modify several different aspects of the brake system for the EG/DC Honda/Acura chassis. Converting to manual brakes via booster delete setup is a first common switch. This can be great for different types of racing that a manual brake system is preferred for a number of reasons. This can help remove the lack of pedal feedback that is characteristic of a booster type system. It can also help you clean up your engine bay and save approximately 10lbs of unnecessary weight.  There's a good chance if you've converted to manual brakes, you have tried different master cylinder bore sizes ranging from 5/8" to 1" bores to get the best pedal feel and stroke for your setup. Some of us have upgraded to a big brake kit with larger rotors and calipers, others choose a small lightweight brake setup for drag racing. Or, maybe a multi-piston caliper setup is the route you've chosen. Regardless of the changes you've made thus far it's likely a pedal ratio adjustment has not been taken into account.

Every variable that we change in the brake system affects our pedal feel, stroke and driver preference. However there has been one variable to the brake system that has been most often neglected. That is the ability to change our pedal ratio. With a factory pedal ratio of 4:1 in these systems there is only so much you can get out of the upgrades and changes you make. Often times the changes you've made leave you upset with the outcome because you are limited to one pedal ratio. You ended up with a harder pedal than you wanted, or you ended up with so little stroke that full engagement seems like you barely move the pedal at all.

WE HAVE YOUR SOLUTION! This Finishing Lines Billet Adjustable Brake Pedal gives you the ability to change that last missing variable to properly setup your custom manual brake setup. The pedal ratio! The pedal comes with two different clevis pieces to connect to the heim joint on the master push rod. One is offset, and by flipping it down you achieve a 6:1 ratio. If you flip it up you get an 8:1 ratio. The second clevis has a zero-offset placing the adjustment in the middle at a 7:1 ratio.

Tech notes:

We suggest you start with the 6:1 ratio and adjust up from there as needed. That is unless you have already researched what is proper for your setup. We have also supplied a table (see pics section) of a few common caliper setups, master bore sizes and pedal ratios that will fall into an acceptable range. The numbers highlighted in yellow fall within the acceptable range. Anything in white is not sufficient and will require added pedal ratio. Please test your changes in a safe manner and exercise caution until you have had time to thoroughly test and decide what ratio is best for your specific setup.
