I need to move an M149A2 water buffalo about 500 miles with no air line hookups. I have checked TM 9-2330-267-14&P and searched Resources and haven't found an answer to my question. If I bleed the air from the trailer tank, will the brakes be released? This trailer was manufactured in 2000, so it is relatively new. I've had someone tell me that if I bleed the tank empty that there is a spring that will force the brakes to engage if the trailer is a newer model, but that with older models, emptying the air tank will in fact release the brakes. First, I don't know what is considered a new or old model M149A2, and second I don't know if the individual I talked to knew what he was talking about. If in fact bleeding the air tank won't release the brakes, can the brakes be caged? The TM does not address this question.
I helped someone recover another model trailer (don't remember the model) about six months ago and that trailer was of fairly new manufacture and it did in fact have the springs that locked the brakes and we had to cage them before the trailer could be pulled withut hookups.
