Brakes locking - advice please.

[Bilgamesh]

My bronco sits in the garage most of the time. I notice when I back it out to get at the mower or something, one or more of the drum brakes wants to lock up. It doesn't seem like it does this when I drive. Do I need to spray some WD-40 on the moving parts to loosen them up some?

A couple of things stand out, the first thing I would do is set it on jack stands check for proper adjustment, then make sure everything is working proper, make sure the E-brake is releasing, however most of the time e-brakes don't work that strong in reverse. Has it been sitting for some time maybe rust on the drums from lack of driving. Next make sure no fluids have leaked onto the shoes, ie. brake or axle.

When a vehicle sits things tend to rust and dirt gets into places you might just have some surface rust on the drums and they lock at slow speed once your out driving they clean off and act normal.

Thanks broncnaz; that sounds like what is happening. Is there any value to adding the WD-40, or would I then just be diminishing the effectiveness of the brakes?

Dont spray anything other than brake cleaner on your brakes.
