stuck rear discs after washing

[HBK]

Hi, I am keen to hear anyone's advice on a problem I have on my 1991 Toyota 4runner....after I wash it, it seems that rust builds up in the rear drum brakes and sticks the brake and the disc together. If the vehicle isn't moved within say 24-48 hours, the bond is so strong that you can't move the bugger and I end up having the remove the back wheels and bash the drums to break the bond. It's happened to me a few times now. Any advice appreciated....

So either go for a quick drive, and use your brakes after washing your wheels.
Or don't put the hand brake on, just leave it in gear.
