I took my 90 Bronco in for a brake checkup, they didn't find anything wrong with it. But whenever I drive the truck on a cold day or wet day, immediately after startup as I start to pull away, a light tap on the brakes will cause full lockup. And I mean light tap, I barely touch the pedal. This goes away after a minute or less of driving. Any ideas? Thanks.
Its flash rust on the drums and rotors. Until the pads rub the flash rust off the surface of the drums and rotors, they will do that. Other than keeping the truck in a dehumidified garage, what can I say... it happens... especially in damp weather. Sometimes turning the rotors and drums will help but not much. Both my 92 and my 93 do it occasionally as did my "Heep" Cherokee.

My truck used to do that all the time. All I can say is to get rid of the Ford drums and shoes. Once I switched to another manufacturer (have no clue what I have, but have run a few different brands over the years) the problem went away. Other than that, get used to driving the first 200 ft with the brakes on to dry them out. I also think not using the parking brake helped since the shoes could dry out better. I do agree that it doesn't take much of a tap to go sliding around!
Awesome thanks for the tips. It makes sense since I leave it parked outside with the e-brake on. I'll swap out the parts next time I need the brakes done.
not using the parking brake doesnt help , i never use mine and its still does it , some other guys on another board suggested lubing the auto adjusters or replacingthem completly .
In my experience replacing the autoadjusters didn't do much. It seemed to be the material the Ford shoes were made of that soaked up moisture. The only thing that fixed my problem was not using the Ford parts.
