Abstract
In a method of forming tamper-resistant brake actuators, the ports for connecting air pressure sources to apertures within the central housing of the brake actuator are bolted to the central housing after the brake housing members have been inelastically deformed together. In this way, the deformation tools utilized to deform the housing members will not contact the air pressure ports. In the past, brake actuators have required spacing the deformation tools from the ports to avoid damaging the ports. This has required that the central housing be undesirably long. With the inventive method, the deformation is performed prior to attachment of the ports. Thus, the axial length of the central housing may be greatly reduced over the prior art. Once the deformation is completed, the ports are then bolted to the central housing. In this way, the length of the central housing and the amount of material required by the central housing are greatly reduced.
