Abstract
A brake actuator for delivering a brake force through a brake block or br pad to a wheel or disc to be braked comprises in a housing (1) a service brake arrangement (3, 5). The actuator also comprises a safety brake arrangement (4, 9) including at least one powerful spring (9), acting in the brake application direction, means for tensioning the spring by the reaction force at a service brake application, and mechanical means (11, 12, 13) for locking the spring to the housing in a tension state. These locking means can be released at will for accomplishing a safety brake application.
