Abstract
Brakes mounted on the wheels of slidably adjustable axles used with truck trailers are connected by a pair of flexible coiled tubes to service and emergency air lines. The flexible coiled tubes are mounted one within the other and have identical end fittings which connect directly to service and emergency air lines and directly to airbrake lines. No intermediate fittings are utilized. The end fittings of each coiled tube are also mounted in fixed relation to a transverse support bracket mounted on the trailer body and to a bracket mounted on a rear axle support. Each end fitting has first, second, and third threaded portions, with the first threaded portion coupled to the end of one of the coiled tubes, the second threaded portion being received through a hole in a bracket, and the third threaded portion being coupled with either an air pressure supply line or an airbrake line.
