Abstract: Brake assemblies and a method of dissipating heat from a brake assembly are provided. A first brake assembly includes a rotor, a brake caliper assembly including an actuator motor, and at least one friction pad operably attached to the caliper assembly. The actuator motor biases the friction pad into frictional engagement with the rotor. At least one thermal conduit extends distally from the actuator motor dissipating heat energy away from the actuator motor. The method includes providing an actuator motor and providing a thermal conduit extending distally from the actuator motor. Heat is conducted away from the actuator motor along the thermal conduit. A second brake assembly includes actuator motor means and thermal conduit means extending distally from the actuator motor means. The brake assembly further includes means for conducting heat from the actuator motor means along the thermal conduit means.

Abstract: An emulator affixed to a brake arm connected to a brake pedal of an electric brake system is capable of emulating a hydraulic brake. The emulator includes a housing defining a fluid chamber containing a magneto-rheological (MR) fluid. A piston is slideably disposed within the piston chamber and a spring biases the piston to resist depression of the brake pedal. A magnetic source generates a magnetic field upon the MR fluid thereby increasing the sheer resistance of the MR fluid further resisting depression of the brake pedal emulating a hydraulic brake system. The amount of resistance can be varied according to the strength of the magnetic field exerted on the MR fluid.
