Abstract: A brake temperature monitoring system configured to monitor at least one of a rotor and hydraulic fluid of a brake mechanism for a vehicle. The system including a controller including a processor and an electronic storage medium, a vehicle velocity sensor, an ambient temperature sensor, and a pre-programmed module. The vehicle velocity sensor is configured to output a velocity signal to the processor. The ambient temperature sensor is configured to output an ambient temperature signal to the processor. The model is pre-programmed into the electronic storage medium, and is adapted to estimate the temperature of at least one of the rotor and the hydraulic fluid. The estimation is based on an ambient air temperature, and a pre-established relationship between a conductive heat transfer factor and a convective heat transfer factor. The convective heat transfer factor is a function of vehicle velocity.

Abstract: A method of estimating brake pad wear includes determining required braking energy to be dissipated by a braking system as a fraction of total kinetic energy according to an energy partitioning model. The required braking energy is distributed to vehicle braking mechanisms according to a vehicle dynamics model. Rotor temperature of each brake rotor may be determined according to a rotor temperature model that utilizes the required braking energy and the distribution of the required braking energy, and determining brake pad wear of each brake pad according to a brake pad wear model that utilizes the rotor temperature and the distributed required braking energy. A first brake pad wear model is implemented under first operating conditions, and a second brake pad wear model under second operating conditions. The brake pad wear is indicated via a brake pad wear indicator output device. A vehicle has a controller that implements the method.

Abstract: A number of variations may include a brake disc may include a hub portion and a cheek portion. The hub portion may include a receiving flange for mechanically engaging the cheek portion. The cheek portion may include an upper cheek and a lower cheek connected and separated by a web, and an inner flange extending radially inward from the upper cheek to mechanically engage and communicate with the receiving flange of the hub portion such that the hub portion and the cheek portion form a single brake disc. The inner flange may include a at least one spline tooth circumferentially arranged around the inner flange and constructed and arranged to facilitate the mechanical engagement of the receiving flange and the inner flange.

Abstract: A brake assembly includes a brake pad, a bracket supporting the brake pad and having a first portion, a second portion spaced apart from the first portion, and a linkage interconnecting the first and second portions. The linkage is configured to transfer tensile loads between the first and second portion, but is characterized by the absence of any bending modes. The absence of bending modes prevents excitation of the linkage, thereby reducing sound generated during application of the brake assembly.
