The Dual Piston Delete’s main difference from the single piston Brake Booster Delete is that it now has 2 isolated braking circuits for front and rear. This means that if you lose a line or experience a leak, you will still have fluid to the other end of the car for braking until you can park and/or get to the pits. It also allows the Brake Booster Delete to be used in its BEST form; Motorsports. Many tracks and series only allow dual or tandem master cylinders, where our single outlet option would be prohibited. To be clear, many stock Master Cylinders have dual outlets but single reservoir feed…so it’s the same assumed risk with OE setups. So all in all our Dual Piston setup is an upgrade that is FD, WRC, NASA, SCCA approved.
The pedal ratio change to 6:1 is the 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 in reference to the piston movement inside. This is beneficial because 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.
If you get in a car with our Dual Piston Brake Booster Delete and Hawk HPS or better brake pads, you will barely notice something is different for normal braking aside from perfectly consistent and linear braking. The noticeable change is in the top 10% of braking before lockup. It requires a tad more leg effort which is beneficial for modulating max braking. Thats where so much value comes in for motorsport use.
