Abstract

A pneumatically actuatable disc brake has a caliper straddling a brake disc. One brake pad on an application side being actuatable by a rotary lever of a brake application device. A brake cylinder, which can be pressurized using air pressure, is attached to a flange of calliper. The brake cylinder engages into the rotary lever via a cylinder plunger and has a return spring for returning the cylinder plunger to an unstressed initial position. The return spring abuts against the base of a cover supported on the flange. The disc brake is configured such that a self-energizing device is provided having a self-energizing factor selected such that the brake automatically releases itself after braking. The flange forms an abutment for the return spring.
