ABSTRACT:
A prior fifth-wheel braking control has a pair of links that support a trailer and rotate a small amount to operate brakes of the trailer to prevent overriding. A toggle or indexing action for stability is obtained by raising the fifth wheel and its load slightly to change positions of the links between a pulling condition and an overriding condition. The present improvement comprises adjustable stops positioned with respect to the links to determine the distance of their forward travel and therefore determine the amount of forward traction to be supplied by a tractor for changing position of the links as required for releasing the brakes of the trailer. The stops have different settings for substantially different weights of trailers to limit the amount of traction required to start the trailers.
