Did I mess up my slack adjusters?

Just wow! That's all I can contribute.

 

Usually only have to raise pin up to back them off. You did it right

 

The thing about auto slacks is they are designed to stay in adjustment by themselves if operating properly.
1-3 full depressions of the pedal stroke keeps them adjusted to correct stroke lengths WITHOUT manual adjustment.

If they are not automatically adjusting, and you are forced to do it manually, it is but a SHORT TERM fix.
They will adjust right back out of whack with travel.

Keep an eye on it. May have to replace it.

 

No worries, Sounds like you over tightened them and had difficulty backing them off. You did the procedure right. NExt time just tighten them without going crazy. I just replaced every single slack adjuster on my truck with haldex aut slack adjusters without the pull up pin and have a ratchet effect. I did so becuase i had a few that kept going out of adjustment. Like someone else that posted, Once you install them, they never need adjustment unless they are wore out. When you do brakes, obviously you have to back them off to get drum off.
Maybe you did your brakes but if not, and they went out of adjustment, just put new ones on. They are inexpensive when it comes to safety and easy to install

 

Thats all the reply some of these company drivers can give becuase they dont work on trucks. They drive for companies

 

And then throw some BS line about being certified or something.

 

You only need to pull the pin to loosen it. As long as you could still pull the pin ( it wasn't bent internally) I think it's going to be fine.

 

Here ya go bud.
