I could hear the brakes screeching on my F250 and made an appt for Thur to get pads and rotors done. No time to do them myself.

Backing out of my daughters drive today one of the front pads fell off in the driveway.

I was surprised since I really had not let the brakes go (very much).

How does a pad fall out of a caliper mounted on the truck? I mean, it's pretty much captive between the caliper bracket and caliper. You can't change pads without removing the caliper.

A WAG is that the friction pad separated from the steel backing plate and fell out.

That would be my guess as well could have rusted out.

If you run the pads down to metal, there is enough of a gap between the caliper and the rotor that they can fall out.

My guess too. I had that happen on a pad that still had 3/4 of the material left. Rustbelt problems. Although 4 years old is a bit early I'd think, on my vehicles around the 5 year mark is where I've seen the start of delamination.

Dang. And people say I'm weird for pulling my brakes apart on a yearly basis--I have to wonder if you have a frozen slider pin or the like to take out a pad that fast.

That pad backing plate looks pretty thin, like it had been like that for some time... I wouldn't drive it now, it must be piston on rotor now.

On the flip side you didn't lose brakes like I did (pedal to the floor until the piston pumped up).

I can only imagine what the condition of the frame and underpinnings must be. Road salt FTW!

I'm having a hard time seeing how this happened.
There's no friction material left at all, and the backing plate is worn severely.

Most people are aware of a brake wear issue before they get to this serious condition.

It was worn down to metal for some time then it was about to wear down to nothing. The screeching sound of metal on metal means replace pads and rotors immediately. You will only get a few stops like that before the final stage where nothing happens when you press the brake pedal.

Hmmmm.... Brake rotors are likely just cast iron or cast steel,

and the brake pads are most likely mild steel - - so probably not so much

So I know I needed brakes, but was not aware I was down to no brake pad. Getting brakes on Thur. Not driving until then except to the shop.

The vehicles gets sprayed yearly with CarWell so no rust on frame or body. Brakes cannot sprayed.
