Abstract: Systems and methods for reducing transient brake caliper drag in a motor vehicle are provided. The motor vehicle, for example, may include, but is not limited to, an axle, a rotor coupled to the axle, a brake caliper comprising a brake pad configured to engage the rotor, a brake pedal assembly communicatively coupled to the brake caliper, the brake pedal assembly configured to receive user input directing the brake pad to apply a force to the rotor and user input directing the brake pad to disengage the rotor, and a processor coupled to the brake caliper, wherein the processor is configured to determine, after the brake pedal assembly receives user input directing the brake pad to disengage the rotor, the force applied to the rotor, and command the brake caliper to retract the brake pad away from the rotor when the determined force exceeds a predetermined threshold.

Abstract: Brake system telemetry systems and methods utilize wireless communication technology to communicate brake system data to one or more vehicle electronic control modules. A wireless transceiver is provided and is operably disposed with the brake system components. The wireless transceiver is coupled to receive data from various components of the brake system at the respective and to communicate the data to one or more electronic control units within the vehicle.
