UBS hydraulic pressure map

The appropriate hydraulic pressure is distributed according to the load being carried by the vehicle. See
figure "A".
The coefficient is set according to the vehicle speed when the brake input starts and remains constant
until the brake input stops. When the brakes are operated continuously to slow the vehicle, the coeffi-
cient (UBS brake force) does not decrease together with the vehicle speed. See figure "B".
