Default AP disc minimum thickness

I've currently got 355x32mm AP 6 pots on the front of my Focus, does anyone know what the minimum thickness of the discs is before they need replacing please?

Thanks, Karl

from ap site:

- 37.00mm Thick discs which have angles vents have a 16mm diameter indicator 1.00mm deep a 12.00 diameter indicator 3.50mm deep and there is a triangle wear indicator that is 6.00mm deep. This indicator shows the direction of rotation of the disc and is the last wear indicator. All these indicators are on both sides of the disc. These are there to give the user a guide as to the disc wear and when the triangle indictors are no longer showing the disc is at or below 25mm its minimum thickness.

- 35.00mm Thick discs that use angles vents have a 12.00mm indicator 2.50m deep and there is a triangle wear indicator that is 5.00mm deep. This indicator shows the direction of rotation of the disc and is the last wear indicator. All these indicators are on both sides of the disc. These are there to give the user a guide as to the disc wear and when the triangle indictors are no longer showing the disc is at or below 25mm its minimum thickness.

- 35.00mm Discs which run non handed vents have a 12.00mm diameter indicator 2.50mm deep and an 8.00mm diameter
indicator 5.00mm deep. When the 8.00mm diameter indicator is no longer visible on both sides this will show the disc at or below its 25.00mm minimum thickness.

NOTE:- In some circumstances one disc face may wear more than the other. If the disc shows signs of this you must make sure you keep a minimum disc thickness of 5.00mm between the outer disc braking face and the inner cooling vent hole in the centre of the discs .

No, the grooves are still there, although the discs are developing a wear lip, which is why I thought I'd ask, thanks

As long as they're still visible and the discs in otherwise good condition, I wouldnt be too worried.
