Trailer wheels are locked up

Bfh

 

With your truck hooked to the trailer, put a chain between the duals loop the chain through the slot in the wheel. run the chain to the back, use another truck to pull like _ _ _ _.

 

^^^^^^^^^^^^

 

Got the gladhands hooked up properly? Hook them up backwards and they probably won't release. Also ran into an issue on a truck once where the actual clevis pin had seized solid to the slack adjuster and the brakes wouldn't release.

 

I usually back off the slacks, if the don't move "persuad" them a little. At least that way you know it's not the cams holding the shoes tight.

 

In the container world we beat the rims with a hammer.

 

I've dealt with a lot of stuck brakes but this seems like a bad idea.

 

That was my first experience with an Allison auto. Jumped in the truck to drive it into the shop for a service and dragged the front left wheels 50 feet along the pavement lol.

 

Have you seen the greasable clevis pins?
