ABSTRACT:
A slack adjuster for a vehicle braking system includes first and second members having a normally reversible screw-thread connection therebetween. The first and second members are disposed between first and second pistons respectively of the braking system and excessive displacement of the pistons causes relative displacement between said first and second member to reduce the displacement of the pistons on the succeeding stroke. One of the first and second members may be a slit or split nut and a wedge member can be provided for urging the slit or split nut against the other of the first and second members to prevent relative rotation therebetween under a brake-applying thrust. The slit or split nut is resiliently biased against the other of the first and second members to prevent undesired relative rotation at the screw-thread connection. The slit nut can be formed as a spring-biased piston designed to prevent over-adjustment due to brake deflection.
