The LC workshop manual says the diameter and thickness of the front brake rotor is 10.625" and 0.375" respectively. This equates to a diameter and thickness of 269.776mm and 9.525mm. The replacement rotors supplied by DBA (Disc brake Australia) and RDA are a diameter of 256mm and thickness of 12.7mm. So they are a smaller diameter but thicker. My concern is will the smaller diameter (13mm) affect brake performance and will the thicker rotor (3.2mm) actually fit inside the caliper, considering the maximum allowable wear in the rotor thickness is about 0.7mm. ??? Something doesn't seem right to me.

Has anyone come across this before?

For one they won't fit in the calliper if they are wider,the XU1 had thicker discs as far as a I know but I would have thought they would have been the same or bigger in diameter,you might have HR discs they have a slightly different offset

I think you'll find the book is wrong.

Thanks guys. If the LC workshop manual is wrong, that would explain it.

Definitely under the L6 disc brake section. Also I believe that the XU1's had thicker discs so did they have different calipers to the standard torana "S" model?
