Right rear chamber caught a rock on a construction site and bent the bracket and rod. Brake was dragging and had to replace.
In-house mechanic replaced it but I cant get him to understand that the rod length is wrong and angle of the slack to rod is off and can get shut down.... I dont even think the top shoe is touching the #### drum.

Help me explain what he did wrong...

Yea we've had a few of our regular f550's get hung up on some of these magic boulders, knocked someone's oil pan the other day.
So the chamber and s-cam bracket are brand new. He swears he cut the rod the same length and I was like, there is no possible way you did. The thing is like 2-3 inches more out of the chamber than the other and the slack angle is like at 45-60 degrees.
Did he cage one and not the other when he measured or is he just full of it? -
Picture with brakes released or applied?
pushbroom Thanks this. -
Looks like the other brake chamber is rusting out.
Did he adjust the slack adjuster, that possible also. -

Not really rusted, it's a construction hauler so its covered in really fine dust, concrete dust, mud, etc. -
Auto slacks typically always want to adjust to a 90 degree applied angle. Cut the pushrod too short, it'll overstroke. Cut it too long and the brakes might end up too tight. I'd verify the brake is properly adjusted before anything else.
