Abstract
A one-nut slack adjuster with a nut axially disposed having clutch surfaces and on non-self-locking engagement on a spindle coaxially positioned within a tube moving axially to apply brakes has a spring biased thrust bearing held forwardly on the nut in the brake application direction disposed to engage a fixed position control member and when the nut is moved axially forwardly a predetermined desired slack distance thereby to bias the nut backwardly. A second trust bearing on this nut is placed forward of the control member to engage it at a distance from rest less than the clutch separation distance. In a double acting embodiment a further trust bearing spring biased between the nut and tube in a position forward of the control member holds the nut in a forward direction in clutch engagement. A further feature is a barrel spring arrangement foreshortening the assembly by a sleeve converting two coaxially disposed spring sections in series.
