Friday on trailer 3129 the s cam bushings were a little loose. We replaced all 6 of them on the triple axial trailer. The reason they get replaced is because if there wiggly or lose the automatic slack adjuster wont be able to adjust right and will cause the breaks to wear unevenly. The fact that we had to replace them made the break job take twice as long as usual. After replacing breaks in the morning we had a trailer that needed to be fixed,it was not legal to cross a scale. The trailer had 9 broken lights a air leak that you could hear and no conspicuity tape"the reflective tap on the bumpers. the lights ended up being a couple bad ground and a bad light.
