The marbles screw loading device is an important structural part in dry disk brakes. With the increasing of braking load and temperature, the material, mechanical and contact performance become a great challenging for the brake design. To better understand the performance, the mechanical and contact performance of marbles screw loading device is investigated. The performance is investigated under different braking load. Then, the influence of typical parameters including geometrical, friction coefficient and temperature on the effective stress and strain is researched. The explicit finite element method is employed to build the numerical simulation model. Numerical simulation result shows that the contact area centre locates on the outside of the brake. The disc groove with 15°has better performance. The residual stress is an increasing with respect to the temperature for the decreasing of material performance. The marbles screw loading device could be largely improved by adjust the geometrical dimensions.
