A brake actuation mechanism for a disc brake including an amplification mechanism, an adjustment mechanism, a thrust element and a return mechanism, which are mountable inside a caliper housing by way of a rod so as to be functionally interacting, in which the adjustment mechanism includes a torque limiting clutch mechanism drivingly connecting several elements and including a first clutch element drivingly connecting a rotatable input element with a rotatable output element and a second clutch element connecting the rotatable output element with the rod, the rotatable output element radially surrounding the first clutch element and the second clutch element. A disc brake including such brake actuation mechanism is also contemplated.
