ABSTRACT:
The invention consists of a slack-adjuster for a brake which comprises a pair of interengaged screw threaded members which are urged towards an extended relative position by an axial bias applied to one member. The screw thread has a high helix angle to permit adjustment to take place on release of the brake and reverse rotation is prevented by frictional engagement of the leading member with a brake applying plunger part and by the use of a saw-tooth screw thread.
