I’ve got an old dry van trailer and right rear brakes caught fire. Pulled wheels and brakes off and inspected. Put new brakes on and wheels back...
sorry I should have clarified, I was called out to this job and they’re just having me replace the valve.
I know this post is old but I have an issue to where I pull the knob out, pins will retract in but knob won’t lock and pins slide back out....
