Last two decades, the researcher is focused on increasing the braking torque of magnetorheological (MR) brake due to the insufficient braking torque to realize in commercial applications particularly vehicle application. Typical methods for enhancing braking torque include improving the rheological characteristics of the carrier fluid, modifying the structure of the MR brake, and raising the strength of the internal magnetic field. Although MR Fluid (MRF) is frequently used in MR brake as a carrier fluid due to its high responsiveness and ease of fabrication, the sedimentation problem has hindered the application of MRF in MR brakes. As a result, MR Grease (MRG) with high viscosity that reduces sedimentation is predicted to overcome the shortcomings of MRF through its unique self-sealing capabilities that efficiently solve the leakage problem. However, the torque performance of MRG is still low which hinder its performance in MR brake application. This review focuses on the usage of MRG instead MRF as a carrier fluid and the improvement of the MRG’s rheological properties which expected to improve the torque performance of MR brake. The factor influencing the rheological properties like the amount, size and shape of magnetic particles are discussed. Furthermore, a few potential additives have been used to improve the rheological properties of MRG and was expected can improved the torque performance of MRG in MR brake are also surveyed and discussed. Therefore, this review will be of significance to MR brake researchers who want to develop a high torque MR brake without occurrence of the sedimentation and leakage.
