1. A brake pad calibration machine, comprising:
a fixture;
a brake pad retainer supported by the fixture and configured to hold a sensorized brake pad relative to the fixture;
an actuator supported by the fixture, the actuator controllable to apply force to the sensorized brake pad, and the calibration machine adjustable to adjust an angle θ between a force direction of the actuator and a plane formed by a surface of a friction element of the sensorized brake pad; and
a controller configured to:
control the actuator to apply force to the sensorized brake pad in the force direction to apply both normal and shear forces to the surface of the friction element of the sensorized brake pad; and
receive one or more signals from one or more force sensors of the sensorized brake pad when the force is applied to the sensorized brake pad; and
generate calibration data based on the signals received from the force sensors when the force is applied to the sensorized brake pad.
