110 HDi brake disc wear

[Martin]

Hi all dose any one know what the recommended minimum thickness of the front discs are. My pads are getting low and not sure if the disc needs to be changed too. The car has now covered 50,000 miles so happy they have lasted this long.

Thanks for any input Martin

All you've got to do now is identify your disc, but what it boils down to is that a maximum of 2mm wear is acceptable.

Hi Dave thanks for the prompt reply I did check them the other day and there was about 3.1mm ware on the sinew disc it is then.
