So I'm not going to list the auction or post pictures, but its so rare to see one local I had to look and see.

Anyway, This is mostly a question, 5 ton truck. 'Brakes frozen'. Really nice picture of GL parking it with skid marks in the gravel. Nice looking truck. Would look better with bows and a cover... But that's just me.

How does one get one of these out of the lot without doing more damage?

What would cause the brakes to be 'frozen' on a 5 ton?

Just curious.

If the brake pads were adjusted too close to the drum they could rust in place. Another option could be a faulty master cyl or air pack. If they were faulty, the brakes could not release after the peddle was stepped on. I'm sure there is more, this is just off the top of my head.

That has air brakes..................correct?

The M939's have full air brakes. NO air the brakes will lock. Add air or "cage" the brakes should get you out ok. Oh and it's only the rear brakes that have the springs so thats why the front are not locked

I was at an unmentioned DRMO and they were trying to load this truck without caging the brakes. I was busy doing my load-out and figured they knew what they were doing, oops, guessed wrong. After this, I did show them how to cage the brakes, you would think that would be Trucker-101.

Explain "Cage the brakes".

The cans have a large spring that apply the brakes when no air exists. Caging is a process where a T shaped bolt in placed in the maxi and a nut is screwed on to release the brakes. Only rear axles have maxis

The air brakes take a release of air to accuate and air pressure to release. If the truck needs to be moved, without air, you would need to cage the brakes. This involves inserting a special bolt to mechanically release the brakes (cage bolt). The cage bolt pulls the mechaism inturn releasing the brakes.
