The state of Nevada, department of conservation and natural resources, division of water resources, purchased four Ford F150 extended cab, short bed, four-wheel drive pickup trucks, with the towing package and automatic transmissions. Budget constraints did not allow the addition of antilock brakes. When the rear brakes become dusty or in the morning when the humidity is higher the rear brakes on all of the trucks tend to lock up under light braking on the pavement. The problem is greater on gravel roads that cover a large portion of the rural parts of Nevada. The rear brakes lock at inopportune times especially on gravel roads that leads to the rear end of the truck wanting to slide out of control. No-one has been injured to date, but it could only be a matter of time before an incident occurs. We have brought the trucks back to Ford under warranty and the rear drums and brakes were replaced, but the problem persists with or without new drums and brake shoes. I've asked about recalls, service bullitins, etc., but have been told that there are none that address this problem.

Parking brake assembly "exploded" in the left rear wheel of my vehicle - incident caused the entire vehicle to shudder as if the rear tire had either blown out or "locked" up.
