Trailer brakes grabbing drum sightly

[Brock]

grease the piss out of it then with your wrench, tighten it all the way, loosen all the way, tighten then back off to proper slack.

try em again.

Every time I've had this happen it was lack of grease causing it to stick while applied.

Crap like that usually happens when otr truckers believe only speedco needs to grease during oil changes.... like they put enough grease into those cams.
