Claim:
A pneumatically or electromechanically actuated disc brake having a brake disc, comprising: a caliper which, in use, straddles the brake disc; a brake application device having a rotary lever and at least one axially movable adjusting spindle, the brake application device being arranged in the caliper; and a drive spindle operatively configured to drive the at least one axially movable adjusting spindle, wherein a crown wheel is rotationally fixed to the drive spindle; a transmission mechanism via which the drive spindle drives the adjusting spindle; and a spur gear segment extending in a pivoting direction of the rotary lever and being integrally connected to the rotary lever, the spur gear segment being arranged to engage the crown wheel, wherein when the rotary lever is actuated the drive spindle drives an axial adjustment of the at least one adjusting spindle, serving to compensate for a wear-induced variation of a lift clearance between a brake pad and the brake disc, the rotary lever is a cast lever, and the drive spindle is rotatably supported between two adjusting spindles, the at least one adjusting spindle comprises two adjusting spindles arranged parallel to and spaced apart from one another.
