Read on here a good while ago, some were having an issue with one brake hanging up. Well went to move my truck a few weeks ago. Left brake was not releasing, when it did it was slow. So being the brake cans were no telling how old. Got a pair $70. for both. Thought I would save myself some time and effort. So took apart the new cans and the old cans. Just swapped out the the can, leaving my old bolted parts to the truck.
Being lazy bit me in the Butt. Yes still hanging up after the new cans. But I did have a little air leak on one pancake gasket. so I did need to change them out anyways. Plus the other one had cracks in it also. So though brake shoes will last 5000 more mines easy. But will just get a new set put on and be done with it.
Shop that put the shoes on, does great work. But when I picked the truck up. Buddy that owns the shop told me. Your not going to believe this. When we got the new brake shoes on. Brake was still hanging up! Over the years he has done many thousands of these jobs. After checking everything on that side again. Come to find out, the back part was the issue. Yes where the rod connects to the slack adjuster. There's a piece that keeps the spring from getting caught where the rod comes though the housing. That part was gone, letting the spring catch. He could push the plunger back by hand and the brake would not hang.
So after redoing my shortcut, all works as it should. Guys I know I have one around 100 of these myself and half of those the shortcut way. When its 0 out and laying in a parking lot. This is also my first time having this issue.
So if you have a brake shoe hanging. With the truck in gear and shut off. Reach under and see if you can push the slack adjuster back in. If so yours has the same issue.
Sad part guess were going to sell our Kenworth T600 now. As were going back to a Ram 3500 and a triple side Truck camper. So guess I will be without the KW soon. Sure hate to see it go, but have a guy that wants to look at it. He pulls RVs for a living with a 53ft trailer. So hate to see him get it in a way. As he will be removing the bed and putting a 5th wheel back on it.
