Variable Brake Booster Controller

MiataSpeed is excited to announce a revolutionary new product in brake system tuning. Many people spend money on big brake kits, braided stainless steel lines, brake pads all in an effort to improve the pedal feel, and modulation characteristics of their brake system. What most people fail to consider is that the brake booster is the single biggest contributor to pedal feel and we've found that it is a largely unexplored tuning area.  As the pedal is applied, the vacuum in the right side of the booster is released and the absolute pressure rises. This causes a pressure differential across the diaphragm and causes a force to be added to the driver's effort. The ratio of the driver's input force to the total output force is referred to as the gain of the booster. As the pressure on the right side of the booster increases it will eventually reach ambient pressure at which point no more pressure can be added to that side. This point is called runout and is the most force that the brake boo
