Ha ha. They have had their moneys worth out of those pads and disks.

My Brother was an HGV mechanic years ago and they had some some Iveco on the fleet. These lorries had a habit of the rear brakes binding while driving down the motorway, wearing through the disk into the vanes then locking the wheel and pulling the lorry off the motorway.
 
Gruesome. Makes me shiver to think people really are that inept/stupid/ignorant.
 
I know! They are those new vented discs! Probably the brake pads causing the problem! ;-))
 
I bet he thought it was just the ABS kicking in
 
Nah there's still some life left in those discs - there's still a friction surface on the in-board face :D
 
Think that's a false picture. looks like on side or the disk has been machined off. Cheers, Tony.
 
That's real, look at the colour of the disk,pad and caliper, also that track rod has hot very hot!

the wear is further in than the pads ?????

Peugeot 206, the owner had been driving the car until the backing plate of the pad fell out! Then continued to use the caliper itself for braking.

Agree with you there Tony, if you look at the pad, it's not as big as the full friction area of the disc, looks like it has been machined off.
 
The pad is skewiff. The bottom edge is covering the inner part of the worn area.

Why would anyone dismantle it, machine it and reassemble it?

No idea what's really going on here or why?

Discs are made from cast iron though and would fracture and crack well before they got to this state, chunks would have flown off all over the place leaving far more damage than's apparent.

That's what leads me to believe it's been machined that way and put back together.

There is more than one type of cast iron.
Cast iron tends to be brittle, except for malleable cast irons. With its relatively low melting point, good fluidity, castability, excellent machinability, resistance to deformation and wear resistance, cast irons have become an engineering material with a wide range of applications and are used in pipes, machines and automotive industry parts.
