Real race car:
When hydraulic pressure is built up, the brake pads are squeezing the discs hard and all mechanical play is compensated. In this stage, your foot is basically pressing against a wall, because now your muscles are pressing directly against the hydraulic forces (the brake fluid). Since the fluid cannot be compressed, you will feel the pedal is hard.
When a racecar driver complains about a “long” or a “soft” pedal, it is typically because there is air in the system, and since air CAN be compressed, the pedal will feel soft and long. The mechanics then bleed the brakes for air, meaning there is only fluid left in the system, and the pedal is once again hard after passing the “soft stage”.
The M.L.C.P.C. System:
To simulate the ‘hard stage’ where it feels like pressing against a concrete wall, we have implemented a rubber damper, which will simulate the fully engaged brake caliper but still enable the load cell sensor to measure additional pedal pressure, which makes perfect trail braking possible. This is the same feeling you get in a real race car.
