Date Nov. 2, 1989.A process is described for positioning the brake pedal during the automatic control mode in an automotive antilocking brake system, in which the pressure in the master cylinder is sensed at a point located where the master cylinder piston sweeps past so that either high or low pressure is sensed depending on the brake pedal position. The pressure sensing is used to generate an electrical signal which is processed in the system controller to it turn generate a control signal transmitted to a pump motor to cause delivery of a volume of fluid to the master cylinder so as to position the brake pedal in the desired position.
