ABSTRACT:
A tool structure is arranged to include a pneumatic chamber with a piston and rod mounted and directed through the chamber coaxially thereof, with a forward end of the rod terminating in a rectilinear plate received through a slot within a pneumatic reservoir of a pneumatic brake organization. The rectilinear plate is arranged for engaging a forward end of a spring member within the pneumatic brake reservoir and its compression therewithin upon application of pneumatic pressure within the tool chamber. A modification of the invention includes an alignment block received within the brake chamber to effect a latching of the engaging plate in a retracted orientation preventing its rotation.
