Agressive Trailer Brakes

My reefer trailer does somewhat the same thing. When empty, I can lock the trailer brakes without even trying but, when it is loaded, I can't get them to hold, to slide the tandems... New brakes and drums.

 

if your trailer is with air ride, just intall and ajust air LSV

 

Good advice so far. We had 1 car hauler that be bought used that had this problem as soon as we got it. The trailer was built with 24/24 chambers and someone replaced them all with 30/30's. 24/24's are common with smaller tire trailers. Once we got the 24's back on, all was well.

Something to check into.

 

I had aggressive trailer brakes once. I did a walk around, kicked the trailer tires and the brake shoe kicked me back.

 

No, aggressive brakes would kick you first. These poor brakes were just defending themselves.

 

laden or unlaiden?
yes check if the trailer is fitted with a lsv. Make sure if it has a lsv that is is fitted the right way round .
the lsv might be set incorrectly so gauge the air pressure on your trucks chambers, then set the lsv to get more or less the same pressure on the trailers brake chambers.
this syncronisation of the tractor and trailer brakes should also enhance better braking distances .
also check for water in the service line of the trailer. (from the suzy hose to the first air valve)
water will make it jerk aswell.
