A brake release mechanism for a spring brake actuator includes a brake release bolt having a threaded portion, a running engaging the threaded portion, the running nut being adapted to axially travel along the threaded portion in order to move a spring brake actuator piston against a force of an actuator power spring, an indicator device comprising an indicator pin being at least partially accommodated in a receiving space of the release bolt, wherein the indicator device further comprises a pin actuator for axially moving the pin relative to the receiving space. It is proposed according to the invention that the pin actuator comprises an indicator cap being attached to the pin, the indicator cap comprising a basic body and at least one spacing element being attached to the basic body, the spacing element being configured to abut against the running nut.
