Rear brakes grab when wet/damp
When there is dew in the morning, my rear brakes grab suddenly when making the first stop of the day. It is very violent. In rainy weather, the first stop will lock up the left rear and I think the right side as well. On dry mornings I don't notice anything abnormal. What causes the brakes to react to moisture this way? Its annoying as hell.

Mine do that also, find that it happens on rainy days or when there is dew on the windsheild (when its not in the garage).
I just drive with the brakes on a little, it goes away quickly.
I know ford had a TSB for their trucks doing it, and it was related to the material of the shoes. (TSB 01192).
in the TSB it states to replace with a different brake kit.

I've only had that happen after going through a car wash and getting the wheel wash option. Moisture gets on the drum and when you apply the brake it's pushing but slipping cause of the water. Then it dries and grabs like hell. I don't know how you'd avoid this just from dew though. I doubt even making sure the star wheel hole had a plug would be enough. Do you set your parking brake? I wonder if having them against the drum for the night would at least give you a dry spot. (assuming they are adjusted properly)

Hmmmmm, so I'm not the only one with this issue. The truck has been acting this way for a year or two, but it got much more violent after having brake work done at Canadian Tire. (I only went there 'cause it was an emergency repair and I was 3 hours from home). 'Guess I'll take it back to them and get it looked at.
