Abstract
A torque sensing apparatus for use with a brake caliper having opposing brake pads positioned on opposite sides of a rotor. The brake caliper causes the brake pads to apply a braking force against the rotor that generates a braking torque. A torque transfer device is supported by the brake caliper and is in contact with one of the brake pads. The torque transfer device is resiliently movable with respect to the brake caliper in response to the braking torque. A torque sensor is positioned in a sensing relationship relative to the torque transfer device. Thus, the torque sensor provides an output signal related to a change of position of the torque transfer device and the braking torque. The torque sensor includes a magnet mounted on the torque transfer device and a magnet field sensor, for example, a Hall Effect sensor, is mounted on the brake caliper.
