Abstract

A pneumatic disc brake includes a caliper which straddles a brake disc, brake pads pressable against the brake disc and a rotary lever actuated brake application device, and a self-energizing mechanism. The brake lever is pivotable about an eccentric axis by a brake cylinder plunger. A self-energizing factor is selected to ensure that the brake automatically releases after braking events. The brake lever is supported on a spherical bearing element mounted to the caliper and forming the eccentric axis. The brake lever bears against a bearing ball which is arranged above the bearing element in the direction of the plunger engagement point, which bearing ball is positioned in a brake ram coupled to the brake pad.
