Chase Bays Dual Piston Brake Booster Delete 6:1 Pedal Ratio

Like anything else on Motorsport chassis, with Manual Brakes, setup is everything. We make a Single Piston and Dual Piston Brake Booster Delete. Where our Single Booster Delete differs; it's a single piston design and its working with the stock 3.5:1 to 4.5:1 pedal ratio (depending on the chassis). The pedal ratio is basically just a way to measure leverage you're giving the master cylinder, it's the distance from the top swinging axis to the brake foot pad divided by the distance from the top swinging axis to the master cylinder clevis mounting point. Our Dual Piston is a 6:1 Pedal Ratio which is what you see on high end motorsport pedal boxes.

Changing the pedal ratio to 6:1 is a major function and feel upgrade to allow the use of a larger master cylinder. The OE pedal ratio can only leverage so much, so we’re limited to a 3/4 or smaller master cylinder. The improved Motorsport pedal ratio gives you a better mechanical advantage with additional leverage. This means we can use a larger 1 inch master cylinder with more fluid being pushed per mm of piston travel inside. It allows you to have a better braking feel and more force to the calipers with equal or lesser force at the pedal. That translates to less leg effort and more braking power while keeping a similar throw distance.
