Adjustable ratio balance bar single brake pedal, in a floor mount assembly. Pedal head adjusts vertically to provide a 5.25, 5.63, or 6.00:1 ratio for more feel or less pedal effort. Two brake master cylinders mount to the assembly, with an adjustable balance bar providing front to rear brake bias fine tuning. The non-skid waffled pedal pad can be laterally adjusted 1/2 inch in either direction for driver preference. The pedal features a lightweight aluminum frame, with high strength reinforced I-beam style forged pedal arm. The balance bar incorporates a positive detent stop every full turn to maintain adjustment position and can be locked in place with the included jam nut, or used with an optional remote knob for quick on-track adjustments. A pin and clevis pushrod attachment system ensures the smallest possible misalignment angle for bind free operation through the entire range of travel. This pedal accepts two Wilwood 2.25 inch vertical mount flange single outlet master cylinders, available separately in a variety of styles and bore sizes.
