Weird disc wear - Mondeo

[Homer]

The previous owner of the car told me the front discs needed changing as there was some shuddering under braking - he wasn't joking!

The passnger side looked fine, very worn and probably original. The driver side inner had some strange wear, there were chunks out of the disc face and the outer edge was worn about 2-3mm, with the wearing getting worse the closer to the outside edge.

Any ideas what could have caused this? There is also a little bit of play in the wheel, so the wheel bearing could do with changing too.

Did it have new pads fitted and were they the right ones? Looks to me like new pads on an old disc, wearing the previous wear lip on the outer edge partially away. Ive never seen the pick up off the friction face like that before though...

Thanks mate. The pads are hardly worn so yes, it looks like they were swapped out and the discs not. They are the correct pads for the car (checked that after seeing the disc!)

The wear on the 3 other faces are perfectly normal and competely flat, just this one face was extremely uneven.

I didn't replace the pads, but I guess this might be a wise option? The pad on that side was also worn unevenly so probably isn't going to do the new disc much good :(

No probs :) Conventional wisdom says you replace the discs and pads as one, and at ford prices its not gonna break the bank lol. Can you put a pic up of the pads on the uneven worn disc? Just out of curiosity :)

I'll get a new set of pads tomorrow and will post up a pic of the pads. There isn't much to see, just some uneven wear. No point scrimping on brakes, especially at Ford (Partco :D ) prices!
