From time to time I will pull my tag a long trailer empty. My biggest fear is locking up the trailer brakes. I've only done it one good time about a year ago while on the phone in a serious conversation while going down a divided highway and the light changed red. It wasn't pretty and it was my fault for not being white knuckled approaching the signal. The smoke and the smell of money and disgust lingers a long time. The other couple times were very minor because my eyes were glued to the road and the light changes to red and I just barely left some rubber and smoke but couldn't let up on the brake pedal. I have also ran a few yellow lights knowing that if I hit the brakes they would lock up. I expect lights to change red and treat them like that but sometimes it's just too much. My trailer is an ABS equipped Eager Beaver 20 ton and I have a lowboy also with ABS but I'm not sure if it works really. Bottom line question is can I disconnect and cap the service line and rely on the truck brakes? Would that be legal if you can do that? I realize you'd have to leave the emergency line connected to keep the brakes open and maybe just use a glad hand with a plug on the service line to keep the air in the system.
My rationale is the trailer only weighs 4 to 5 tons and the truck is designed to carry 18 tons on the truck brakes alone. That way if a light changes red or a car pulls out in front of you you could smash down on the brakes hard and stop yourself a lot quicker and safer than locking up 8 tires on the empty trailer. Also you could potentially ruin $2k to $3k in tires.
Also an empty tag a long being 4tons and an empty lowboy usually being 8tons or more is a different story. The tag a long is going to lock up much easier during a big braking situation.
