modified brake pedal: Why I chose the Whitby power brake kit
I picked the Whitby Power Brake option somewhat as an afterthought. Originally I planned electric power steering with a manual rack. However, the Coyote was much too wide for the ePowersteering option. As a result, I had to change plans. That choice also shaped the brake option. Should I go hydraulic with Powerboost? Or vacuum assist? Ultimately I chose Whitby vacuum assist. So why is this post about a modified brake pedal?
Pedal angle problem on a Coyote
Pedal sits too low and angled
The Whitby Power Brake setup mates to the Wilwood pedal box. It even includes a new brake pedal arm. It is about 90% finished. Also, I changed to Mike Everson spacers and Lodestone Billetworks billet aluminum master cylinder nipples from LS Billetworks. Still, one item needs work: the brake pedal angle. I contacted them several times. In a Coyote setup, the brake pedal sits substantially lower in the footbox. It sits lower than the clutch and accelerator. Therefore this layout is just dangerous! Imagine going for the brake but hitting the gas. Here is a pic of the setup. The pedal is about 3″ deeper than the other two. Likewise, it angles downward about 20 degrees. Extremely unsafe!
Why we built up the pedal pad
Thankfully there are some remedies. Some builders heat the brake pedal and bend it. However, that is hard once the pedal box is nearly finished. Another choice clocks the hinge angle and resets the pin. Again, that is tough with the box mounted. So we built up the lower section where the pedal mounts.
Fortunately my son is deep into 3D printing and setup testing. Also, our friend BradC has a CNC machine and 3D skills. First we ran several mockups. Then Brad CNC’d aluminum and we used carbon impregnated PETG. Here are some pics!
Final spacing with Forte pedal covers
It became a 2–3 day loop of measure, print, and test. As a result, the three pedals now share equal side spacing. They also share the same depth. Next I fitted new pedal spacers and covers from Mike Forte.
