Abstract: An automatic slack adjuster for a cam-operated brake is disclosed. The adjustment mechanism includes a pair of torquelimiting clutch springs. One spring limits adjustment to a predetermined torque level so that large actuating forces generated during a brake application will not overload the adjustment mechanism. The other clutch spring insures that the adjuster will not ''''back off'''' after an adjustment is effected. The adjuster is designed so that manual adjustment may also be effected, either to adjust the brakes or to back the brakes off without disconnecting any part of the automatic adjuster mechanism.
