As a long-time Ford owner and mechanic, I thought I'd toss something in about squealing Ford brakes. The tenth picture down shows the old and new brake pads. I would expect by what I see in that photo that the original poster's brakes were NOT making noise. I arrive at that conclusion because I can see the anti-squeal shims are still adhered to the pads. If you look very close, you will see a thin metal shim stuck to the back of all the pads. Looking closer, you can see the shims beginning to de-laminate from the old pads while they are stuck tightly to the new ones, making them very hard to see. Motorhome usually don't get many miles on them compared to cars and because of that, time, rather than mileage takes it's toll on the rubbery glue that holds the shims to the back on the pads. When the shim comes completely unbonded (they will fall out on the floor when you slip the pads out of the caliper), the brakes will start making the dreaded high-pitched squeal when stopping even though the pads may still be in very good shape. I think the shims are 'vulcanized' to the pads so re-attaching them isn't very likely but the good news is that just replacing the pads with new will instantly stop the squeal. Ford has used that caliper/pad design for decades and whether it's a light duty pickup or dual-piston HD truck, The symptom, cause and cure are the same. De-laminated anti-squeal shims are the culprit. My off-hand guess is that ten years is about all the glue lasts and that even with little mileage on a rig, the pads will need to be replaced to stop the noise. Kind of a pain that such a simple thing will make such a racket but to Ford's credit, I've never seen squealing Ford truck brakes where the shims were still adhered. I also want to add important safety info. BE SURE to securely the chock wheels on Ford trucks with rear disk brakes and work on a LEVEL surface!! These trucks have a driveshaft mounted parking brake that, when you jack up one rear wheel, becomes useless as the differential will allow the wheel still on the ground to turn once the other wheel is jacked up even though the driveshaft is immobilized by the parking brake!! VERY IMPORTANT!!
