The MagnaShear motor brake employs oil-shear technology, which eliminates wear on friction surfaces. Oil shear also provides a smooth “cushioned” stop, which reduces shock to the drive system. A fluid-recirculation system dissipates heat – a problem in dry braking systems.

Oil-shear technology includes a layer of automatic transmission fluid between the brake disc and the drive plate. As the fluid is compressed, the fluid molecules shear, thus imparting torque to the other side. This causes the stationary surface to turn, bringing it up to the same relative speed as the moving surface. Because most of the work is done by the fluid particles in shear, wear is virtually eliminated, which, in turn, eliminates the need for adjustments.
