Zusammenfassung:	An automatic adjuster for a vehicle brake mechanism comprises a force transmitting mechanism having two members with a non-reversible screw-thread connection therebetween. To effect automatic adjustment responsively to excess brake travel, a spring acts axially upon balls rolling along the screw-thread on one of the members or on a separate thread of the same pitch on that member and causes the ball to roll along the thread. The balls are located in a recess in the other member so that as it is urged along the thread it rotates the other member to effect the necessary adjustment. The balls, therefore, effectively provide a reversible screw-thread connection between the two members for the purpose of effecting adjustment.
