So , to me this is a default from a piece that regulate the air pressure in function of the load of the trailer (which gives a constant maximal pressure to the trailer)
I'm a truck mecanic . The trailer is connected to the truck by 2 air cables. When truck brakes , air is sent to the trailer by one of the cable , the other cable is constantly air pressured (to the trailer's tank) But here's not ! . This is not because the cable is broken , else the trailer would constantly brakes as it is a security (need at least one pressure to brake after the rapture), and generally lock the truck on the spot (heavy weight trailers behind of course)
It has nothing to do with 'too strong' of brakes. An empty trailer or chassis will almost always not have enough weight for the brakes to not lock up the tires. If you ever see smoke pouring from a semi (which happens a lot) be prepared!
The trailer has a brake control mechanism to make it brake when the truck does. it is adjusted for the case of the trailer carrying a load. It comes on too strong when there is no weight on the trailer.
I find it amazing that every time someone is video taping the video is quite still until something happens then it goes everywhere with mass confusion.. Its ridiculous. You'd think it would be the other way around..
@Vallecrash they generally do have abs but that doesnt mean they still wont lock to some degree or even work at all. how many cars heave u seen with the abs light on, trucks have the same problems.
Yeah, it's just that the trailer doesn't have a cargo box on it. Without the weight the wheels are really easy to lock up. Typically there is an adjustment. But if it's air brakes you can't just turn the pressure down. The air pressure holds the brakes OFF. Releasing the pressur turns them on. So, you basically adjust how much air it let's off to the trailer for a given pedal input.
so, its not that the brakes are strong, the trailer is what was skidding like that, the fact is that, like any empty trailer, it had no load to bear and when the brakes, that are normally used to stop big loads, are hit they lock due to the little resistance they are designed for....
it happened to me to.. in driving school. the brakes were set on fully loaded but the trailer wasn't loaded. the trailer just jumped half of meter to the left. O_O
I bet you he just forgot to set the suspension back to driving position! That's how you make the brakes more sensitive, cause by leaving the suspension down after unloading container, you manipulate the brakes to believe that the trailer is loaded, and if you lift it all the way on the suspensions, you won't manage to lock them at all...
@21cglock they dont have electronic brakes. they have air brakes and if u disconnect air brakes the brakes remained locked. this is a safety feature so if a truck looses air pressure the brakes lock instead of having a runaway truck.
@rfs12345 Your right... I saw a regular pick up trailer with electric brakes.But i saw wrong! lol thanks for the correction. I thought it was a rental moving truck with a 5000lb weight trailer.
Even with automatic brake systems, empty trailers will easily block.
If the trailer usually has at least an empty rig/container on it, the brakes will be more worn down to that "empty-rig-weight" than the last distance to the "empty-without-rig-weight".
Also, most people know to brake harder to make a heavy thing slide. Lighter things on the opposite slide easier.
on some trucks you can adjust the sensitivity of the trailer brake applicatioon. turn it up when the trailer is full - turn it down when its empty. being that this one is a skel and weighs bugger all isnt helping the problem esspecially if he has just unloaded it and hasnt turned the brakes down. easy to forget
Thats not how it works, the air holds a big spring open on the brakes, you need a lot of air pressure to hold them open, if u turn down the air pressure your gonna close the breaks.
ThundareRed... compressed air in a brake chamber? no kidding! wow! why would you "turn down the air pressure" midway through a trip anyway? i think you may not quite have the knowledge required to make an accurate assumption here...
well then that would be me that you were replying to... the reason i know that you can adjust the "sensitivity of the trailer brake applicatioon" is because i drive a truck every day which has a system capable of doing it. one of its purposes is to aid in avoiding what has happened in this video
i hope you understand about the way AirBrakes work, As soon the air is release from the brake chamber, the chamber is caged, coil spring is fully engauged
thats because the trailer brakes are normed for the trailer with loading. The ABS gets activated when the truckwheels are blocking (at older trucks like this one)
What makes you suspect the ABS is failing? Certainly the lack of weight is a factor, but I find when trailer brakes lock up like that while the other brakes function normally is a result of brake valve with a crack-pressure that is too low for its placement along the brake system. It's a common mistake made by techs working on dollies and similar equipment.
Well i know that relay valve crack pressures in trailers are usually lower by a pound or two than on the tractor so you don't have the effect of being "pushed" by your trailer. Lol that could be what you are saying in your comment, i'm just a little slow and had a hard time understanding what you wrote.
Generally, the wheel's shouldn't lock up like this at all, even if the chassis is unloaded. If the wheels are locking, then either the ABS, if equipped, isn't working or an air valve along the system is malfunctioning or has the wrong spec. Trailers, and empty chassis, shouldn't behave like the ones in the video.
the trailer was too light if it had more weight like an empty container it woulda kept more grip and prehaps too much brake pressure issued by foot

ive seen it all the time here, if its missing the load the trailer weighs nothing from the brakes point of view and they smoke like that.
You see it on the highway all the time when trucks stop to prevent accidents, the trailer or usually empty is smoking the tires.

You may be right. Perhaps the crack pressure for a valve closer earlier along the system may have a crack pressure that's too high.

is it possible that truck is loaded, and it needs more breaking power, and since trailer is empty this results with wheels blocking?
